description
The TLC4501 and TLC4502 are the highest precision CMOS single supply rail-to-rail operational amplifiers
available today. The input offset voltage is 10 µV typical and 40 µV maximum. This exceptional precision,
combined with a 4.7-MHz bandwidth, 2.5-V/µs slew rate, and 50-mA output drive, is ideal for multiple
applications including: data acquisition systems, measurement equipment, industrial control applications, and
portable digital scales.
These amplifiers feature self-calibrating circuitry which digitally trims the input offset voltage to less than 40 µV
within the first 300 ms of operation. The offset is then digitally stored in an integrated successive approximation
register (SAR). Immediately after the data is stored, the calibration circuitry effectively drops out of the signal
path, shuts down, and the device functions as a standard operational amplifier.

†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only , and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may af fect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to VDD –/GND.
2. Differential voltages are at IN+ with respect to IN–. Excessive current flows when an input is brought below VDD– – 0.3 V.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.

APPLICATION INFORMATION
D
The TLC4502 is designed to operate with only a single 5-V power supply , have true dif ferential inputs, and
remain in the linear mode with an input common-mode voltage of 0.
D
The TLC4502 has a standard dual-amplifier pinout, allowing for easy design upgrades.
D
Large differential input voltages can be easily accommodated and, as input dif ferential-voltage protection
diodes are not needed, no large input currents result from large differential input voltage. Protection should
be provided to prevent the input voltages from going negative more than –0.3 V at 25°C. An input clamp
diode with a resistor to the device input terminal can be used for this purpose.
D
For ac applications, where the load is capacitively coupled to the output of the amplifier, a resistor can be
used from the output of the amplifier to ground. This increases the class-A bias current and prevents
crossover distortion. Where the load is directly coupled, for example in dc applications, there is no crossover
distortion.
D
Capacitive loads, which are applied directly to the output of the amplifier, reduce the loop stability margin.
Values of 500 pF can be accommodated using the worst-case noninverting unity-gain connection. Resistive
isolation should be considered when larger load capacitance must be driven by the amplifier.
The following typical application circuits emphasize operation on only a single power supply. When
complementary power supplies are available, the TLC4502 can be used in all of the standard operational
amplifier circuits. In general, introducing a pseudo-ground (a bias voltage of VI/2 like that generated by the
TLE2426) allows operation above and below this value in a single-supply system. Many application circuits
shown take advantage of the wide common-mode input-voltage range of the TLC4502, which includes ground.
In most cases, input biasing is not required and input voltages that range to ground can easily be
accommodated.
description of calibration procedure
To achieve high dc gain, large bandwidth, high CMRR and PSRR, as well as good output drive capability, the
TLC4502 is built around a 3-stage topology: two gain stages, one rail-to-rail, and a class-AB output stage. A
nested Miller topology is used for frequency compensation.
During the calibration procedure, the operational amplifier is removed from the signal path and both inputs are
tied to GND. Figure 35 shows a block diagram of the amplifier during calibration mode.

Figure 35. Block Diagram During Calibration Mode
The class AB output stage features rail-to-rail voltage swing and incorporates additional switches to put the
output node into a high-impedance mode during the calibration cycle. Small-replica output transistors (matched
to the main output transistors) provide the amplifier output signal for the calibration circuit. The TLC4502 also
features built-in output short-circuit protection. The output current flowing through the main output transistors
is continuously being sensed. If the current through either of these transistors exceeds the preset limit (60 mA
– 70 mA) for more than about 1 µs, the output transistors are shut down to approximately their quiescent
operating point for approximately 5 ms. The device is then returned to normal operation. If the short circuit is
still in place, it is detected in less than 1 µs and the device is shut down for another 5 ms.
The offset cancellation uses a current-mode digital-to-analog converter (DAC), whose full-scale current allows
for an adjustment of approximately ±5 mV to the input offset voltage. The digital code producing the cancellation
current is stored in the successive-approximation register (SAR).
During power up, when the offset cancellation procedure is initiated, an on-chip RC oscillator is activated to
provide the timing of the successive-approximation algorithm. To prevent wide-band noise from interfering with
the calibration procedure, an analog low-pass filter followed by a Schmitt trigger is used in the decision chain
to implement an averaging process. Once the calibration procedure is complete, the RC oscillator is deactivated
to reduce supply current and the associated noise.

APPLICATION INFORMATION
The key operational-amplifier parameters CMRR, PSRR, and offset drift were optimized to achieve superior
offset performance. The TLC4502 calibration DAC is implemented by a binary-weighted current array using a
pseudo-R-2R MOSFET ladder architecture, which minimizes the silicon area required for the calibration
circuitry, and thereby reduces the cost of the TLC4502.
Due to the performance (precision, PSRR, CMRR, gain, output drive, and ac performance) of the TLC4502, it
is ideal for applications like:
D
Data acquisition systems
D
Medical equipment
D
Portable digital scales
D
Strain gauges
D
Automotive sensors
D
Digital audio circuits
D
Industrial control applications
It is also ideal in circuits like:
D
A precision buffer for current-to-voltage converters, a/d buffers, or bridge applications
D
High-impedance buffers or preamplifiers
D
Long term integration
D
Sample-and-hold circuits
D
Peak detectors
The TLC4502 self-calibrating operational amplifier is manufactured using Texas instruments LinEPIC process
technology and is available in an 8-pin SOIC (D) Package. The C-suffix devices are characterized for operation
from 0°C to 70°C. The I-suffix devices are characterized for operation from –40°C to 125°C. The M-suffix
devices are characterized for operation from –55°C to 125°C.

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.
