MAX14628 Description

The MAX14627/MAX14628 provide a simple solution for detecting the insertion and managing the operation of a 3.5mm stereo headset with a microphone. These devices integrate all circuitry needed to detect SEND/END button press events and generate required microphone bias voltages, and are fully patible with Windows Mobile 7. The devices need only three GPIOs from the host controller to select between call mode and...
