DESCRIPTION

10mW at 5V, 250kHz

4mW at 2.7V, 200kHz

The ADS8326 is a 16-bit, sampling, analog-to-digital

2mW at 2.7V, 100kHz

(A/D) converter specified for a supply voltage range

0.2mW at 2.7V, 10kHz

from 2.7V to 5.5V. It requires very little power, even

when operating at the full data rate. At lower data

•

Pin-Compatible with the ADS7816, ADS7822,

The ADS8326 offers excellent linearity and very low

ADS7826, ADS7827, ADS7829, ADS8320, and

noise and distortion. It also features a synchronous

Low power and small size make the ADS8326 ideal

for portable and battery-operated systems. It is also a

fit

for

modules,

simultaneous multichannel systems, and isolated

data acquisition. The ADS8326 is available in either

an MSOP-8 and an SON-8 package.
