DESCRIPTION
The
potentiometer. The wiper position is controlled with a
simple
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 10kΩ,
50kΩ, and 100kΩ. All CAT5126 devices have
32-wiper positions and operate from a single 2.5V to
5.5V supply.
The CAT5126 is available in TDFN 8-pad and MSOP
8-lead packages. Each device is guaranteed over the
industrial temperature range of -40°C to +85°C.
