CAT5126

CAT5126 One-Time Digitally Programmable 32 Tap Potentiometer FEATURES „ Wiper position stored after one-time nonvolatile programming „ User-defined Power-On wiper position „ 32 tap positions „ Wiper position programmed through simple 2-wire serial interface „ Low 0.35µA (typ) static supply current „ 2.5V to 5.5V single-supply operation „ 10kΩ, 50kΩ, and 100kΩ end-to-end resistances „ 50ppm/°C end-to-end temperature coefficient and 5ppm/°C ratiometric temperature coefficient „ 8-Pin TDFN (2mm x 3mm) and MSOP packages 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 onetime 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 8-pin TDFN and MSOP packages. Each device is guaranteed over the industrial temperature range of -40°C to +85°C. For Ordering Information details, see page 10.
