The ISL90841 is a chip that integrates four digitally controlled potentiometers (XDCP). It features low noise, low power, and an I2C bus interface. Each potentiometer can be controlled by the user through the I2C bus interface. The chip can be widely used in control, parameter adjustment, and signal processing.
The ISL90841 integrates four digitally controlled potentiometers (XDCP) in a 14‑lead TSSOP package. Each potentiometer provides 256 resistor taps with 0.4 % resolution and is controlled via a standard I²C (12C) serial interface.
The device operates from 2.7 V to 5.5 V, supports a standby current of less than 5 µA, and is specified for industrial temperature ranges from –40 °C to +85 °C. It is RoHS‑compliant and available in two resistance options (10 kΩ and 50 kΩ).
