Description
The DA7217 is a high-performance, low power audio codec optimized for use in headsets or wearable devices. It has differential headphone outputs for use inside headset devices, offering excellent left to right channel separation and common mode noise rejection. DA7217 also has a stereo DAC to headphone output path and ultra-low power operating modes to support always-on audio detect applications.
DA7217 contains two analog microphone input paths, or up to four digital microphone input paths, or a combination of both. The other chip in this family, the DA7218, has single-ended headphone outputs, and has been designed with headphone detect for use in accessories.
Benefits
- Superior hi-fidelity audio performance for immersive record and playback
- Sub 500µW always-on power extends battery life for audio activity detection
- Flexible programming filtering (sideband, voice) enhances voice and audio playback
- Mixed sample rate support for wideband applications
- Supports the latest generation of low power analog and digital microphones
- Small package footprint with an optimized ballout conducive to low cost PCB manufacturing

DA7217 Register Setting
Hi, We just started a new design based on DA7217. The design uses two analog mics and I2S out to a host processor. No headphone is used. I wonder if there are any application notes about setting up the registers for this codec. Thanks, Jimmy ADS Inc.
