Powered by GS/AI

The AK4954AEN is a low power 32-bit stereo CODEC designed for portable applications requiring recording and playback functionality. It features a microphone amplifier with automatic level control (ALC) and a cap-less headphone amplifier, along with a speaker amplifier capable of driving loads directly from battery voltages ranging from 0.9V to 5.5V. The device supports a wide range of sampling frequencies from 8kHz to 96kHz and offers various digital audio interface formats, including I¬=S. The CODEC includes two low noise microphone power supplies, multiple input selectors, and a digital microphone interface. For playback, it provides a digital volume control and dynamic range control circuit. The headphone amplifier delivers an output power of 20mW at 16Oc, while the speaker amplifier can output up to 400mW at 8Oc. The device is packaged in a compact 32-pin QFN format, making it suitable for space-constrained designs. Overall, the AK4954AEN is a versatile solution for audio applications requiring high-quality sound processing in a small footprint.
