Description
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.
Benefits
- GND/MIC polarity switch and multiple button detection for CTIA/OMTP audio jacks
- 7.5mm2 package footprint enabling PCB space savings in area constrained applications
- Capless headphone driver eliminates large AC coupling capacitors
- Optimized ball-out conducive for low cost PCB manufacturing
Advanced Accessory Detection (AAD)
Image
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.
