Ultra-Low Power Stereo Codec with Differential Headphone Driver

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.
