[AK7757] AK7757 Audio DSP with 24bit 3ch ADC + 4ch DAC + MIC Amp GENERAL D ESCRIPTION The AK7757 is a d igital signal processor with an integrated 4ch DAC, a stereo AD C with input selector, a mono ADC and an integrated digital au dio interface. The audio D SP has 1536 step/fs (at 48kHz sampling) parallel arithmetic operation performance. As the AK7757 is a R AM based DSP, it is programmable for user requirements to realize the audio e ffects process or th e proprietary high-performance HF. It is housed in a 48pin LQFP which is a small package to save the PCB space. FEATURES † DSP - Word length: 24bits (Da ta RAM: F24floating point) - Processing Speed: 13.
