DESCRIPTION

The ADS8325 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 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. For

example, the average power dissipation is less than

1mW at a 10kHz data rate.

The ADS8325 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

within the range of 2.5V to VDD.

Low power and small size make the ADS8325 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 ADS8325 is available in

MSOP-8 and SON-8 packages. The SON package

size is the same as a 3x3 QFN package.
