Description

The AK4616 is a single chip audio CODEC that includes three channel ADCs and five channel DACs. The analog inputs support differential/single-ended with 4:1 stereo selector in front of 2-channel 99dB ADC, and monaural ADC for guidance sound. The high performance 5-channel DAC integrates full-range digital volume control and achieves 105dB dynamic range. A car audio system can be easily designed with an audio DSP and the AK4616. The AK4616 is housed in a space saving 48-pin LQFP package.
