DESCRIPTION
The ADS8322 is a 16-bit, 500kHz Analog-to-Digital (A/D)
converter with an internal 2.5V reference. The device in-
cludes 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 –40
°C to +85°C temperature
range.
