Description

The AK7757 is a digital signal processor with an integrated 4ch DAC, a stereo ADC with input selector, a mono ADC and an integrated digital audio interface. The audio DSP has 1536 step/fs (at 48kHz sampling) parallel arithmetic operation performance. As the AK7757 is a RAM based DSP, it is programmable for user requirements to realize the audio effects process or the proprietary high-performance HF. It is housed in a 48pin LQFP which is a small package to save the PCB space .
