ADS8321

SBAS123B – SEPTEMBER 1999 – REVISED SEPTEMBER 2004

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 con-

verter (ADC) with tested 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 dissipa-

tion is less than 1mW at 10kHz data rate.

ꢀ 100kHz SAMPLING RATE

ꢀ MICRO POWER:

4.5mW at 100kHz

1mW at 10kHz

ꢀ POWER DOWN: 3µA max

ꢀ MSOP-8 PACKAGE

The ADS8321 also features a synchronous serial (SPI/SSI

compatible) interface, and a differential input. The refer-

ence voltage can be set to any level within the range of

500mV to V_CC/2.

ꢀ PIN-COMPATIBLE TO ADS7816 AND 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 modules, simulta-

neous multi-channel systems, and isolated data acquisi-

tion. The ADS8321 is available in an MSOP-8 package.
