Description and Introduction
16bit stereo CODEC with built-in Microphone-amplifier and 16bit Mono CODEC for Bluetooth Interface. The AK4641EN is a low-power stereo CODEC manufactured by Asahi Kasei Microdevices (AKM). It supports a wide range of audio sampling rates from 8 kHz to 48 kHz and features a built-in microphone amplifier, headphone amplifier, and digital volume control. The device operates on a single 1.8V power supply and is designed for portable audio applications. It includes a 24-bit stereo ADC and DAC, with a signal-to-noise ratio (SNR) of 95 dB for the ADC and 90 dB for the DAC. The AK4641EN also supports multiple audio interfaces, including I2S, left-justified, and right-justified formats. It is available in a 24-pin QFN package.
