General Description

The MAX11041/MAX11042 wired remote controllers convert up to six or 30 different pushbuttons into an I2C register. Together with low-cost pushbutton switches and 1 resistors, the MAX11041/MAX11042 are total solutions over a single-wire interface. A wired remote controller easily piggybacks to a standard 3.5mm headphone jack using a fourth contact or one of the audio signals
