DESCRIPTION
The ADS8321 is a 16-bit sampling analog-to-digital
converter with guaranteed specifications over a 4.75V
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 1mW at
10kHz data rate.
The ADS8321 also features a synchronous serial
(SPI/SSI compatible) interface, and a differential in-
put. The reference voltage can be set to any level
within the range of 500mV to 2.5V.
Ultra-low power and small size make the ADS8321
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 ADS8321 is available in
an 8-lead MSOP package.
