CAT5140:Digital Potentiometer (POT), 256-Tap, I2C Compatible
The CAT5140 is a single channel non-volatile 256-tap digital POT. This digital POT is comprised of a series of equal value resistor elements connected between two externally accessible end points. The tap points between each resistive element can be selectively connected to the wiper output via internal CMOS switches forming a linear taper electronic potentiometer.
