description

The TLV2541, TLV2542, and TLV2545 are a family of high performance, 12-bit, low power, miniature, CMOS

analog-to-digital converters (ADC). The TLV254x family operates from a single 2.7-V to 5.5-V supply. Devices

are available with single, dual, or single pseudo-differential inputs. Each device has a chip select (CS), serial

clock (SCLK), and serial data output (SDO) that provides a direct 3-wire interface to the serial port of most

popular host microprocessors (SPI interface). When interfaced with a TMS320t DSP, a frame sync signal (FS)

can be used to indicate the start of a serial data frame on CS for all devices or FS for the TLV2541.

TLV2541, TLV2542, and TLV2545 are designed to operate with very low power consumption. The power saving

feature is further enhanced with an autopower-down mode. This product family features a high-speed serial link

to modern host processors with SCLK up to 20 MHz. The maximum SCLK frequency is dependent upon the

mode of operation (see Table 1). The TLV254x family uses the built-in oscillator as the conversion clock,

providing a 3.5-μs conversion time.

detailed description

The TLV2541, TLV2542, and TLV2545 are successive approximation (SAR) ADCs utilizing a charge

redistribution DAC. Figure 1 shows a simplified version of the ADC.

The sampling capacitor acquires the signal on AIN during the sampling period. When the conversion process

starts, the SAR control logic and charge redistribution DAC are used to add and subtract fixed amounts of charge

from the sampling capacitor to bring the comparator into a balanced condition. When the comparator is

balanced, the conversion is complete and the ADC output code is generated.

pseudo-differential inputs

The TLV2545 operates in pseudo-differential mode. The inverted input is available on pin 5. It can have a

maximum input ripple of ±0.2 V. This is normally used for ground noise rejection.

control and timing

start of the cycle

Each cycle may be started by either CS, FS, or a combination of both. The internal state machine requires one

SCLK high-to-low transition to determine the state of these control signals so internal blocks can be powered

up in an active cycle. Special care to SPI mode is necessary. Make sure there is at least one SCLK whenever

CS (pin 1) is high to ensure proper operation.

TLV2541

DControl via CS ( FS = 1 at the falling edge of CS)—The falling edge of CS is the start of the cycle. The MSB

should be read on the first falling SCLK edge after CS is low. Output data changes on the rising edge of

SCLK. This is typically used for a microcontroller with an SPI interface, although it can also be used for a

DSP. The microcontroller SPI interface should be programmed for CPOL = 0 (serial clock referenced to

ground) and CPHA = 1 (data is valid on the falling edge of the serial clock). At least one falling edge transition

on SCLK is needed whenever CS is brought high.

DControl via FS (CS is tied/held low)—The MSB is presented after the rising edge of FS. The falling edge

of FS is the start of the cycle. The MSB should be read on the first falling edge of SCLK after FS is low. This

is the typical configuration when the ADC is the only device on the DSP serial port.

control and timing (continued)

DControl via both CS and FS—The MSB is presented after the falling edge of CS. The falling edge of FS is

the start of the sampling cycle. The MSB should be read on the first falling SCLK edge after FS is low. Output

data changes on the rising edge of SCLK. This configuration is typically used for multiple devices connected

to a TMS320 DSP.

TLV2542/5

All control is provided using CS (pin 1) on the TLV2542 and TLV2545. The cycle is started on the falling edge

transition provided by either a CS signal from an SPI microcontroller or FS signal from a TMS320 DSP. Timing

is similar to the TLV2541, with control via CS only.

TLV2542 channel MUX reset cycle

The TLV2542 uses CS to reset the analog input multiplexer. A short active CS cycle (4 to 7 SCLKs) resets the

MUX to AIN0. When the CS cycle time is greater than 7 SCLKs in duration, as in the case for a complete

conversion cycle (CS is low for 16 SCLKs plus maximum conversion time), the MUX toggles to the next channel

(see Figure 4 for timing). One dummy conversion cycle is recommended after power up before attempting to

reset the MUX.

sampling

The converter sample time is 12 SCLKs in duration, beginning on the fifth SCLK received after the converter

has received a high-to-low CS transition (or a high-to-low FS transition for the TLV2541).

conversion

The TLV2541, TLV2542, and TLV2545 complete conversions in the following manner. The conversion is started

after the 16th SCLK falling edge and takes 3.5 μs to complete. Enough time (for conversion) should be allowed

before a rising CS or FS edge so that no conversion is terminated prematurely.

TLV2542 input channel selection is toggled on each rising CS edge. The MUX channel can be reset to AIN0

via CS as described in the earlier section and in Figure 4. The input is sampled for 12 SCLKs, converted, and

the result is presented on SDO during the next cycle. Care should also be taken to allow enough time between

samples to avoid prematurely terminating the cycle, which occurs on a rising CS transition if the conversion is

not complete.

The SDO data presented during a cycle is the result of the conversion of the sample taken during the previous

cycle.

using CS as the FS input

When interfacing the TLV2541 with the TMS320 DSP, the FSR signal from the DSP may be connected to the

CS input if this is the only device on the serial port. This saves one output terminal from the DSP. (Output data

changes on the falling edge of SCLK. This is the default configuration for the TLV2542 and TLV2545.)

using CS as the FS input (continued)

SCLK and conversion speed

The input frequency of SCLK can range from 100 kHz to 20 MHz maximum. The ADC conversion uses a

separate internal oscillator with a minimum frequency of 4 MHz. The conversion cycle takes 14 internal oscillator

clocks to complete. This leads to a 3.5-μs conversion time. For a 20-MHz SCLK, the minimum total cycle time

is given by: 16x(1/20M)+14x(1/4M)+one SCLK = 4.35 μs. An additional SCLK is added to account for the

required CS and/or FS high time. These times specify the minimum cycle time for an active CS or FS signal.

If violated, the conversion terminates, invalidating the next data output cycle. Table 1 gives the maximum SCLK

frequency for a given supply voltage and operational mode.

control via pin 1 (CS, SPI interface)

All devices are compatible with this mode operation. A falling CS initiates the cycle (for TLV2541, the FS input

is tied to VDD). CS remains low for the entire cycle time (sample+convert+one SCLK) and can then be released.

NOTE:

IMPORTANT: A single SCLK is required whenever CS is high.

control via pin 1 (CS, DSP interface)

All devices are compatible with this mode of operation. The FS signal from a DSP is connected directly to the

CS input of the ADC. A falling edge on the CS input initiates the cycle. (For the TLV2541, the FS input can be

tied to VDD, although better performance can be achieved when using the FS input for control. Refer to the next

section.) The CS input should remain low for the entire cycle time (sample+convert+one SCLK) and can then

be released.

NOTE:

IMPORTANT: A single SCLK is required whenever CS is high. This should be of little consequence,

since SCLK is normally always present when interfacing with a DSP.

control via pin 1 and pin 7 (CS and FS or FS only, DSP interface)

Only the TLV2541 is compatible with this mode of operation. The CS input to the ADC can be controlled via a

general-purpose I/O pin from the DSP. The FS signal from the DSP is connected directly to the FS input of the

ADC. A falling edge on CS, if used, releases the MSB on the SDO output. When CS is not used, the rising FS

edge releases the MSB. The falling edge on the FS input while SCLK is high initiates the cycle. The CS and

FS inputs should remain low for the entire cycle time (sample+convert+one SCLK) and can then be released.

reference voltage

An external reference is applied via VREF

. The voltage level applied to this pin establishes the upper limit of the

analog inputs to produce a full-scale reading. The value of VREF and the analog input should not exceed the

positive supply or be less than GND, consistent with the specified absolute maximum ratings. The digital output

is at full scale when the input signal is equal to or higher than VREF and at zero when the input signal is equal

to or lower than GND.

power down and power up

Autopower down is built into these devices in order to reduce power consumption. The actual power savings

depends on the inactive time between cycles and the power supply (loading) decoupling/storage capacitors.

Power-down takes effect immediately after the conversion is complete. This is fast enough to provide some

power savings between cycles with longer than 1 SCLK inactive time. The device power goes down to 5 μA

within 0.5 μs. To achieve the lowest power-down current (deep powerdown) of 1 μA requires 2-ms inactive time

between cycles. The power-down state is initiated at the end of conversion. These devices wake up immediately

at the next falling edge of CS or the rising edge of FS.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability

information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between

the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight

in homogeneous material)

(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other

changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All

semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time

of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily

performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered

documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support

that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which

anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause

harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use

of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to

help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and

requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties

have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in

military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components

which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and

regulatory requirements in connection with such use.

TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which

have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such

components to meet such requirements.
