Resources for DA7218
Description
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
