16-Bit, High Speed, MicroPower Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● BIPOLAR INPUT RANGE

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.

● 100kHz SAMPLING RATE

● MICRO POWER:

4.5mW at 100kHz

1mW at 10kHz

● POWER DOWN: 3µA max

● 8-LEAD MSOP PACKAGE

● PIN-COMPATIBLE TO ADS7816 AND

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.

ADS7822

● SERIAL (SPI/SSI) INTERFACE

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.
