AKM AK4616单片音频24位CODEC解决方案
AKM公司的AK4616是单片音频24位CODEC,集成了三路ADC和五路DAC,模拟输入支持差分/单端输入.ADC的S/N达到99dB,S/(N+D)为88dB,取样频率从8kHz到48kHz.DAC动态范围105dB,集成了全范围数字音量控制,和音频DSP就能构成汽车音频系统.本文介绍了AK4616主要特性,框图以及评估板AKD4616-A功能,框图和电路图.
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.
