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 multi-
channel 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.
