... The MAX5409/MAX5411 are dual poten- tiometers with two wipers per potentiometer (see Functional Diagram). An SPI™-compatible serial inter- face controls the wiper positions. The MAX5408– MAX5411 have a factory-set resistance of 10kΩ per potentiometer. A zero-crossing detect feature mini- mizes the audible noise generated by wiper transitions. ...

... Detailed Description Digital Serial Interface An SPI-compatible serial interface controls the MAX5408–MAX5411. The input word to the device is eight bits long, composed of three address bits (A0, A1, and A2), followed by five data bits, with MSB first (see Tables 1 and 2). The first three address bits set the value of internal registers ...
