X9400 Datasheet (Renesas) - Quad Digitally Potentiometer

X9400, Quad Digitally Potentiometer

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.

X9400 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-vol
