CAT5133:Digital Potentiometer (POT), 256-Tap, I2C Compatible
The CAT5133 is a high voltage digital POT integrated with EEPROM memory and control logic to operate in a similar manner to a mechanical potentiometer. The digital POT 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. A 7-bit wiper control register (WCR) independently controls the wiper tap switches for the potentiometer. Associated with the control register is a 7-bit nonvolatile memory data register (DR) used for storing the wiper settings. Changing the value of the wiper control register or storing that value into the nonvolatile memory is performed via a 3input Increment-Decrement interface.
