Intersil X9409 Manuals

The X9409 is a low noise, low power, 2-wire bus quad digitally controlled potentiometer (XDCP). It features four potentiometers per package with 64 resistor taps. It supports a 2-wire serial interface for write, read, and transfer operations of the potentiometer. The operating voltage range is from 2.7V to 5.5V. It has non-volatile data registers and non-volatile storage of multiple wiper positions. The saved wiper position is loaded on power-up.
