High-performance, low-power audio codec

DA7218is a high-performance, low-power audio codec optimized for use in portable applications or wearable devices. It has single-ended headphone outputs with headphone detect for use in accessories, offering excellent left to right channel separation and common mode noise rejection.

DA7218also has a stereo DAC to headphone output path and ultra-low power operating modes to support always-on audio detect applications. It 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 DA7217 has differential headphone outputs without headphone detect, and has been designed for use inside headset devices.
