The ISL90841 incorporates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digital control potentiometer is composed of resistance element and CMOS switch. The wiper position is controlled by the user through the i2c bus interface. Each potentiometer has an associated wiper register (WR) that can be written and read directly by the user.
Functional Diagram
The content of the WR controls the position of the wiper. All four potentiometers have a terminal connected to GND. dcp can be used in resistance voltage dividers or variable resistors at both ends for a wide range of applications, including control, parameter adjustment and signal processing
