Description

The AK7757VQ is a digital signal processor with an integrated 4 channel 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 AK7757VQ is a RAM based DSP, it is programmable for user requirements to realize the audio effects process or the proprietary high-performance HF. 
The AK7757VQ is housed in a 48-pin LQFP which is a small package to save the PCB space.

Applications
