DESCRIPTION
The ADS8322 is a 16-bit, 500kHz Analog-to-Digital (A/D)
converter with an internal 2.5V reference. The device in-
cludes a 16-bit capacitor-based Successive Approximation
Register (SAR) A/D converter with inherent sample-and-
hold. The ADS8322 offers a full 16-bit interface, or an 8-bit
option where data is read using two read cycles and 8 pins.
The ADS8322 is available in a TQFP-32 package and is
guaranteed over the industrial –40°C to +85°C temperature
range.

ELECTROSTATIC
DISCHARGE SENSITIVITY
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.
