DESCRIPTION
The CAT5133 is a high voltage Digital Programmable Potentiometer (DPP) integrated with E2PROM memory and control logic to operate in a similar manner to a mechanical potentiometer. The DPP consists of a series of resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper outputs with CMOS switches.

FEATURES
■ Single linear DPP with 128 taps
■ End-to-end resistance of 10kΩ, 50kΩ or 100kΩ
■ 2-wire interface
■ Fast Up/Down wiper control mode
■ Non-volatile wiper setting storage
■ Automatic wiper setting recall at power-up
■ Digital Supply range (VCC): 2.7V to 5.5V
■ Analog Supply range (V+): +8V to +16V
■ Low Standby Current: 15μA
■ 100 Year wiper setting memory
■ Industrial Temperature range: -40ºC to +85ºC
■ RoHS-compliant 10-pin MSOP package
