説明

The 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. 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.

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
