DESCRIPTION
The ADS7816 is a 12-bit, 200kHz sampling analog-
to-digital converter. It features low power operation
with automatic power down, a synchronous serial
interface, and a differential input. The reference volt-
age can be varied from 100mV to 5V, with a corre-
sponding resolution from 24µV to 1.22mV.
Low power, automatic power down, and small size
make the ADS7816 ideal for battery operated systems
or for systems where a large number of signals must be
acquired simultaneously. It is also ideal for remote
and/or isolated data acquisition. The ADS7816 is
available in an 8-pin plastic mini-DIP, an 8-lead SOIC,
or an 8-lead MSOP package.
