Digital Potentiometer 256POS 10KOhm Quad 14-Pin TSSOP

The ISL90841 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the I 2C bus interface. Each potentiometer has an associated 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. All four potentiometers have one terminal tied to GND. The DCPs can be used as a resistor divider or as two-terminal variable resistors in a wide variety of applications including control, parameter adjustments, and signal processing.
