Digital Potentiometers (POTs) | CAT5126

The CAT5126 is a digital POT. The wiper position is controlled with a simple 2-wire digital interface. This digital POT 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 kΩ, 50 kΩ, and 100 kΩ. All CAT5126 devices have 32 wiper positions and operate from a single 2.5 V to 5.5 V supply.

Each device is guaranteed over the industrial temperature range of -40°C to +85°C.
