Summary
16 Volt Digitally Programmable Potentiometer (DPP) with 128 Taps and I2C Interface July, 2010 ??Rev. 5
Description
The CAT5132 is a high voltage digital POT with non-volatile wiper setting memory, operating like a mechanical potentiometer. The tap points between the 127 equal resistive elements are connected to the wiper output via CMOS switches. The switches are controlled by a 7-bit Wiper Control Register (WCR). The wiper setting can be stored in a 7-bit non-volatile Data Register (DR). The WCR is accessed via the I2C serial bus.
