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.
