DA7219
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.
Key features
■ High performance mono microphone to ADC
record path with 90 dB SNR
□ ADC digital filters with audio and voice
mode high-pass characteristics
□ A low-noise microphone bias regulator
with programmable output
■ High performance stereo DAC to headphone
playback path with 100 dB SNR
□ DAC digital filters with audio and voice
mode high-pass cut-off and 5-band
equaliser
■ Advanced Accessory Detection supports
□ Three/four pole jack detection
□ MIC/GND polarity switching
□ Multiple button detection
□ Headphone impedance testing
■ A microphone input with ALC (automatic
level control)
■ Digital Sidetone path with gain
■ Digital tone generator
■ System controller for simplified pop-free
start-up and shutdown
■ Single interface 24 kHz ADC/48 kHz DAC
mixed sample rates supported
■ Shutdown mode for very low current
consumption during standby
■ Phase locked loop with sample rate
tracking to generate system clock
■ 4-wire digital audio interface with support
for I2S, TDM and other audio formats
■ 2-wire I2C compatible with support for
High Speed mode up to 3.4 MHz
■ WL-CSP RouteEasy™ package for low
cost PCB manufacture
Applications
■ Chromebooks
■ Portable audio applications
■ Tablets and eBooks
■ Headphone accessories
■ Remote controllers
■ Gaming controllers
