APPLICATIONS
DESCRIPTION
The CAT5126 is a digital programmable
potentiometer. The wiper position is controlled with a
simple 2-wire digital interface. This digital
potentiometer is unique in that it has an optional one-
time programmable feature that either sets the wiper’s
position upon power-on to a user-defined value, or the
wiper can be set and the interface also disabled to
prevent further adjustment.
The CAT5126 has an end-to-end resistance of 10k,
50k, and 100k. All CAT5126 devices have 32
wiper positions and operate from a single 2.5V to 5.5V
supply.
The CAT5126 is available in 8-pin TDFN and MSOP
packages. Each device is guaranteed over the
industrial temperature range of -40°C to +85°C.
