3 Description

The ADS8320 device is a 16-bit, sampling analog-todigital

(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 an

8-pin VSSOP package.
