X9400 - Quad Digitally Potentiometer

Datasheet Summary

Description

The X9400 integrates four digitally controlled potentiometers (XDCPs) on a monolithic CMOS integrated circuit.

The digitally controlled potentiometer is implemented using 63 resistive elements in a series array.

Between each element are tap points connected to the wiper terminal through switches.

Features

Four potentiometers per package.
64 resistor taps.
SPI serial interface for write, read, and transfer operations of the potentiometer.
Wiper resistance, 40 typical at 5V.
Four non-volatile data registers for each potentiometer.
Non-volatile storage of multiple wiper position.
Power-on recall. Loads saved wiper position on power-up.
Standby current < 1µA max.
System Analog VV+C/VC:.
