ADS8323

DESCRIPTION

The ADS8323 is a 16-bit, 500kSPS Analog-to-Digital Con-

verter (ADC) with an internal 2.5V reference. The device

includes a 16-bit capacitor-based SAR ADC with inherent

sample-and-hold. The ADS8323 offers a full 16-bit interface,

or an 8-bit option where data is read using two read cycles.

The ADS8323 is available in a TQFP-32 package and is

specified over the industrial –40

°C to +85°C temperature

range.
