Renesas Electronics Corporation Single, 128-Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™) ISL23418UFUZ-TK

The ISL23418 is a volatile, low voltage, low noise, low power, SPI™ bus, 128 taps, single digitally controlled potentiometer (DCP), which integrates DCP core, wiper switches, and control logic on a monolithic CMOS integrated circuit.brbr The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wiper is controlled by the user through the SPI bus interface. The potentiometer has an associated volatile Wiper Register (WR) that can be directly written to and read by the user. The contents of the WR controls the position of the wiper. When powered on, the ISL23418 wiper always commences atbrmid-scale (64-tap position).brbr The low voltage, low power consumption, and small package size of the ISL23418 make it an ideal choice for use in battery operated equipment. The ISL23418 has a VsubLOGIC/sub pin allowing down to 1.2V bus operation, independent from the VsubCC/sub value. This allows for low logic levels to be connected directly to the ISL23418 without passing through a voltage level shifter.brbr The DCP can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.
