DESCRIPTION

The ADS8317 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.

The ADS8317 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 0.1V to VDD/2.

Low power and small size make the ADS8317 ideal

for portable and battery-operated systems. It is also

an excellent fit for remote data-acquisition modules,

simultaneous multichannel systems, and isolated

data acquisition. The ADS8317 is available in

MSOP-8 and SON-8 packages. The SON package size is the same as a 3x3 QFN package.
