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 V_DD/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.
