DESCRIPTION
The ADS8322 is a 16-bit, 500kHz analog-to-digital
(A/D) converter with an internal 2.5V reference. The
device includes 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 are
read using two read cycles and eight pins. The
ADS8322 is available in a TQFP-32 package and is
ensured over the industrial –40°C to +85°C
temperature range.
