Wcd9341 Datasheet __exclusive__ -

Converts digital data into rich analog sound for headphones and captures analog voice/audio into digital data for storage.

Requires external 2.2 µF bootstrap capacitor on CP_OUT and 4.7 µF on VDD_CP . Missing these causes audible thumps.

Drivers engineered for both high-efficiency speaker output and ultra-low-distortion headphone playback. Technical Specifications and Performance wcd9341 datasheet
