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.
