ADS8322  
SBAS215 JULY 2001  
16-Bit, 500kHz, MicroPower Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
HIGH-SPEED PARALLEL INTERFACE  
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.  
500kHz SAMPLING RATE  
LOW POWER: 85mW at 500kHz  
INTERNAL 2.5V REFERENCE  
UNIPOLAR INPUT RANGE  
TQFP-32 PACKAGE  
The ADS8322 is available in a TQFP-32 package and is  
guaranteed over the industrial –40°C to +85°C temperature  
range.
