Audio Codec with Advanced Accessory Detect Evaluation Kit
The DA7219-EVAL evaluation board has been designed to allow measurement and functional testing of the DA7219 ultra-low power audio codec with advanced accessory...
The DA7219 is an ultra-low power audio codec with Advanced Accessory Detection (AAD), which supports sample rates up to 96kHz 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.
The AAD will detect a jack insertion/removal, detect the polarity of the jack (CTIA/OMTP), and will support the detection of impedance based buttons in parallel with the connected accessory microphone.
