Audio codec with Advanced Accessory Detect

Company confidential

General description

The DA7219 is an audio codec with Advanced Accessory Detection (AAD).

DA7219 contains a mono microphone to ADC path, and a stereo DAC to HP path.

The AAD block supports three-pole (headphone) and four-pole (headset) jacks, and allows the

automatic pin order switching of MIC/GND on CTIA or OMTP headsets. It also supports automatic

button detection.
