DA7218

Ultra-Low Power Stereo Codec

GeneralDescription

DA7218 is 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.

DA7218 also has a stereo DAC to headphone output path and ultra-low power operating modes to

support always-on audio detect applications.

DA7218 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, theDA7217 has differential headphone outputs

without headphone detect, and has been designed for use inside headset devices.

Key Features
