Details
The AK4642 features a stereo CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier and Speaker-Amplifier. Input circuits include a Microphone-Amplifier and an ALC (Auto Level Control) circuit that is suitable for portable application with recording/playback function. The AK4642 is available in a 32pin QFN, utilizing less board space than competitive offerings. Features1.
