ISL23318 Single, 128-taps Low Voltage Digitally Controlled Potentiometer (XDCP™) DATASHEET The ISL23318 is a volatile, low voltage, low noise, low power, I2C Bus™, 128 Taps, single digitally controlled potentiometer (DCP), which integrates DCP core, wiper switches and control logic on a monolithic CMOS integrated circuit.

The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches.

The position of the wipers are controlled by the user through
