DESCRIPTION  
The ADS8320 is a 16-bit, sampling analog-to-digital (A/D) converter with ensured specifications over a 2.7-V to  
5.25-V supply range. It requires very little power even when operating at the full 100-kHz data rate. At lower data  
rates, the high speed of the device enables it to spend most of its time in the power-down mode—the average  
power dissipation is less than 100 mW at 10-kHz data rate.  
The ADS8320 also features operation from 2 V to 5.25 V, a synchronous serial (SPI/SSI compatible) interface,  
and a differential input. The reference voltage can be set to any level within the range of 500 mV to VCC  
.
Ultra-low power and small size make the ADS8320 ideal for portable and battery-operated systems. It is also a  
perfect fit for remote data acquisition modules, simultaneous multi-channel systems, and isolated data  
acquisition. The ADS8320 is available in 8-pin ceramic surface-mount packages, specified for the –55°C to  
210°C temperature range.
