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 is read using two read cycles and 8 pins. The ADS8322 is available in a TQFP-32 package and is guaranteed over the industrial \x9640°C to +85°C temperature range.
