The X9250 is a quad digitally controlled potentiometer (XDCP) integrated circuit that provides four 256-tap potentiometers in a single package.

Key Features

The device features a low noise, low power SPI bus interface, with a standby current of less than 5 μA (total package).

Each potentiometer has four nonvolatile data registers and a volatile wiper counter register, allowing for flexible control and storage of wiper positions.

The device operates with a wide power supply range of 2.7V to 5.5V and has a high reliability endurance of 100,000 data changes per bit per register.


The X9250 can be used in a variety of applications, including control, parameter adjustments, and signal processing, as a three-terminal potentiometer or as a two-terminal variable resistor.
