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.
