Intersil X9409 Quad Digitally Controlled Potentiometer Datasheet

The Intersil X9409 integrates four digitally controlled potentiometers (XDCP) on a single monolithic CMOS integrated microcircuit. Each potentiometer is implemented using 63 resistive elements in a series array, providing 64 resistor taps. The device features a 2-wire serial interface for write, read, and transfer operations, allowing the user to control the wiper position via a host system.

The X9409 includes four non-volatile data registers for each potentiometer, enabling the storage of multiple wiper positions. Upon power-up, the device recalls the saved wiper position from these registers. Key features include a typical wiper resistance of 50Ω at 5V, a system voltage range of 2.7V to 5.5V, and low power consumption with a standby current of less than 1pA typical. The device is available in 24-lead SOIC and TSSOP packages and is RoHS compliant.
