microPower:

DESCRIPTION

10mW at 5V, 250kHz

4mW at 2.7V, 200kHz

2mW at 2.7V, 100kHz

0.2mW at 2.7V, 10kHz

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

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

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

when operating at the full 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. For

example, the average power dissipation is less than

0.2mW at a 10kHz data rate.

MSOP-8 and SON-8 Packages

(SON-8 package same as 3x3 QFN)

16-Bit Upgrade to the 12-Bit ADS7816 and

ADS7822

Pin-Compatible with the ADS7816, ADS7822,

ADS7826, ADS7827, ADS7829, ADS8320, and

ADS8325

The ADS8326 offers excellent linearity and very low

noise and distortion. It also features a synchronous

serial (SPI/SSI-compatible) interface and a differential

input. The reference voltage can be set to any level

•

Serial ( SPI™/SSI) Interface

within the range of 0.1V to V_DD

Low power and small size make the ADS8326 ideal

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

perfect fit for remote data-acquisition modules,

simultaneous multichannel systems, and isolated

data acquisition. The ADS8326 is available in either

an MSOP-8 and an SON-8 package.
