DESCRIPTION
The ADS8326 is a 16-bit, sampling, analog-to-digital
(A/D) converter specified for a supply voltage range
from 2.7V to 5.5V. It requires very little power, even
when operating at the full data rate. At lower data
rates, the high speed of the device enables it to
spend most of its time in the power-down mode. For
example, the average power dissipation is less than
0.2mW at a 10kHz data rate.
The ADS8326 offers excellent linearity and very low
noise and distortion. It also features a synchronous
serial (SPI/SSI-compatible) interface and a
differential input. The reference voltage can be set to
any level within the range of 0.1V to VDD.
Low power and small size make the ADS8326 ideal
for portable and battery-operated systems. It is also
a perfect fit for remote data-acquisition modules,
simultaneous multichannel systems, and isolated
data acquisition. The ADS8326 is available in an
MSOP-8 package.

This integrated circuit can be damaged by ESD. Texas Instruments 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.
