DESCRIPTION
The ADS7826/27/29 is a family of 10/8/12-bit sampling
analog-to-digital converters (A/D) with assured specifi-
cations at 2.7-V supply voltage. It requires very little
power even when operating at the full sample rate. At
lower conversion rates, the high speed of the device
enables it to spend most of its time in the power down
mode— the power dissipation is less than 60 µW at 7.5
kHz.
The ADS7826/27/29 also features operation from 2.0 V
to 5 V, a synchronous serial interface, and a differential
input. The reference voltage can be set to any level
within the range of 50 mV to VCC.
Ultra-low power and small package size make the
ADS7826/27/29 family ideal for battery operated sys-
tems. It is also a perfect fit for remote data acquisition
modules, simultaneous multichannel systems, and iso-
lated data acquisition. The ADS7826/27/29 family is
available in a 3 x 3 8-pin PDSO (SON, same size as
QFN) package.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
