DATASHEET ISL23415 Single, Low Voltage Digitally Controlled Potentiometer (XDCP™) FN7780 Rev.3.00 Mar 17, 2022 The ISL23415 is a volatile, low voltage, low noise, low power, SPI™ bus, 256 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 controlle
