AK7712 Built-in 20-bit ADC/DAC Sophisticated Audio DSP

The AK7712A is a DSP(Digital Signal Processor) with built-in high performance 20bit 2ch ADC and 4ch DAC, on purposeto control the sound field. It is possible to calculate 383 steps on 44.1kHz and 48kHz sampling respectively. In case of 32kHz sampling, it can caluculate up to 511 steps. With a combin.
