DESCRIPTION
The ADS7808 is a complete 12-bit sampling analog-to-digital
using state-of-the-art CMOS structures. It contains a 12-bit
capacitor-based SAR A/D with S/H, reference, clock, and a
serial data interface. Data can be output using the internal
clock, or can be synchronized to an external data clock. The
ADS7808 also provides an output synchronization pulse for
ease of use with standard DSP processors.
The ADS7808 is specified at a 100kHz sampling rate, and
specified over the full temperature range. Laser-trimmed
scaling resistors provide various input ranges including ±10V
and 0V to 5V, while an innovative design operates from a
single +5V supply, with power dissipation under 100mW.
The ADS7808 is available in a 0.3" SO-20, fully specified for
operation over the industrial –40°C to +85°C range.

This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

NOTES: (1) LSB means Least Significant Bit. For the ±10V input range, one LSB is 4.88mV. (2) Typical rms noise at worst case transitions and temperatures.
(3) As measured with fixed resistors in Figure 4. Adjustable to zero with external potentiometer. (4) For bipolar input ranges, full scale error is the worst case of
Full Scale or +Full Scale untrimmed deviation from ideal first and last code transitions, divided by the transition voltage (not divided by the full-scale range) and
includes the effect of offset error. For unipolar input ranges, full scale error is the deviation of the last code transition divided by the transition voltage. It also includes
the effect of offset error. (5) All specifications in dB are referred to a full-scale ±10V input. (6) Full-Power Bandwidth defined as Full-Scale input frequency at which
Signal-to (Noise + Distortion) degrades to 60dB. (7) Recovers to specified performance after 2 x FS input overvoltage. (8) The minimum VIH level for the DATACLK
signal is 3V.

7 AGND2 Analog Ground.
8 SB/BTC Select Straight Binary or Binary Twos Complement data output format. If HIGH, data will be output in a Straight Binary format. If
LOW, data will be output in a Binary Twos complement format.
9 EXT/INT Select External or Internal Clock for transmitting data. If HIGH, data will be output synchronized to the clock input on DATACLK. If
LOW, a convert command will initiate the transmission of the data from the previous conversion, along with 12 clock pulses output
on DATACLK.
10 DGND Digital Ground.
11 SYNC Synch Output. If EXT/INT is HIGH, either a rising edge on R/C with CS LOW or a falling edge on CS with R/C HIGH will output a
pulse on SYNC synchronized to the external DATACLK.
12 DATACLK Either an input or an output depending on the EXT/INT level. Output data will be synchronized to this clock. If EXT/INT is LOW,
DATACLK will transmit 12 pulses after each conversion, and then remain LOW between conversions.
13 DATA Serial Data Output. Data will be synchronized to DATACLK, with the format determined by the level of SB/BTC. In the external clock
mode, after 12-bits of data, the ADS7808 will output the level input on TAG as long as CS is LOW and R/C is HIGH (see Figure 3.) If
EXT/INT is LOW, data will be valid on both the rising and falling edges of DATACLK, and between conversions DATA will stay at the
level of the TAG input when the conversion was started.
14 TAG Tag Input for use in external clock mode. If EXT/INT is HIGH, digital data input on TAG will be output on DATA with a delay of 12
DATACLK pulses as long as CS is LOW and R/C is HIGH. See Figure 3.
15 R/C Read/Convert Input. With CS LOW, a falling edge on R/C puts the internal sample/hold into the hold state and starts a conversion.
When EXT/INT is LOW, this also initiates the transmission of the data results from the previous conversion. If EXT/INT is HIGH, a
rising edge on R/C with CS LOW, or a falling edge on CS with R/C HIGH, transmits a pulse on SYNC and initiates the transmission of
data from the previous conversion.
16 CS Chip Select. Internally ORed with R/C.
17 BUSY Busy Output. Falls when a conversion is started, and remains LOW until the conversion is completed and the data is latched into the
output shift register. CS or R/C must be HIGH when BUSY rises, or another conversion will start without time for signal acquisition.
18 PWRD Power Down Input. If HIGH, conversions are inhibited and power consumption is significantly reduced. Results from the previous
conversion are maintained in the output shift register.
19 VANA Analog Supply Input. Nominally +5V. Connect directly to pin 20, and decouple to ground with 0.1µF ceramic and 10µF Tantalum
capacitors.
20 VDIG Digital Supply Input. Nominally +5V. Connect directly to pin 19. Must be VANA.

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.
