ISL23315
Single, Low
Voltage Digitally Controlled Potentiometer (XDCP™)
FN7778 Rev 2.00 August 12, 2015
The ISL23315 is a volatile, low
voltage, low noise, low power, I2C 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 controlled by the user through the I2C 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 ISL23315’s wiper will always commence at mid-scale (128 tap position).
The low
voltage, low power consumption, and small package of the ISL23315 make it an ideal choice for use in battery operated equipment. In addition, the ISL23315 has a VLOGIC ...
