DESCRIPTION
The ADS8320 is a 16-bit sampling analog-to-digital
converter (A/D) with guaranteed specifications over a
2.7V to 5.25V supply range. It requires very little
power even when operating at the full 100kHz 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
100µW at 10kHz data rate.
The ADS8320 also features operation from 2.0V to
5.25V, a synchronous serial (SPI/SSI compatible) in-
terface, and a differential input. The reference voltage
can be set to any level within the range of 500mV to
V
CC
.
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 mod-
ules, simultaneous multi-channel systems, and iso-
lated data acquisition. The ADS8320 is available in
an MSOP-8 package.
