CAT5126_13 Datasheet, PDF (1/9 Pages) ON Semiconductor – One‐time Digital 32‐tap Potentiometer (POT)

CAT5126
One‐time Digital 32‐tap
Potentiometer (POT)
Description
The CAT5126 is a digital POT. 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 10 kW, 50 kW, and
100 kW. All CAT5126 devices have 32-wiper positions and operate
from a single 2.5 V to 5.5 V 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.
