The X95840 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. It features low noise, low power consumption, I2C bus interface, and 256 taps resolution. The position of the wipers can be controlled by the user through the I2C bus interface, and it can be used in various applications such as control, parameter adjustments, and signal processing.
The X95840 integrates four digitally controlled potentiometers (XDCP) on a single CMOS chip. Each potentiometer offers 256 resistor taps with 0.4 % resolution and can be used as a three‑terminal potentiometer or a two‑terminal variable resistor.
The device operates from 2.7 V to 5.5 V, features a standby current below 5 µA, and provides non‑volatile storage of wiper positions. It includes an I²C‑compatible serial interface with up to eight devices per bus and supports both volatile and non‑volatile register access.
