DA7219-02VBA Dialog Semiconductor

DA7219 Audio Codec with Advanced Accessory Detect General Description The DA7219 is an ultra low-power audio codec with Advanced Accessory Detection (AAD), which supports sample rates up to 96 kHz at 24-bit resolution. It contains a mono microphone to analog to digital converter (ADC) path, and a stereo digital to analog converter (DAC) to headphone (HP) path. AAD supports the detection and identification of 3-pole (headphone) and 4-pole (headset) jacks, and allows the automatic pin order switching of MIC/GND on CTIA or OMTP headsets. It also supports automatic multiple button detection.
