DATASHEET ISL23325 Dual, 256-Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™) FN7870 Rev 1.00 September 23, 2015 The ISL23325 is a volatile, low voltage, low noise, low power, 256-Tap, dual digitally controlled potentiometer (DCP) with an I2C Bus™ interface.

It integrates two DCP cores, wiper switches and control logic on a monolithic CMOS integrated circuit.

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