AK7755 Datasheet - AKM

AK7755 DSP

The AK7755 is a highly integrated digital signal processor, including a mono ADC, a stereo audio CODEC, a MIC pre-amplifier, a line-out amplifier and digital audio I/F. The audio DSP has 2560step at fs = 48kHz parallel processing power. As the AK7755 is a RAM based DSP, it is programmable for user r.
