[AK7735] AK7735 Dual DSP with 4chADC + 4chDAC + 4chSRC 1. General Description The AK7735 is a highly integrated digital signal processor, including a 24-bit stereo ADC with MIC gain amplifiers, a 24-bit stereo ADC with input selector, two 32-bit stereo DACs, 2 stereo sampling rate convertors supporting the sampling frequency up to 192kHz and dual DSPs for Audio/HF process. Each DSP has 3072step/fs (when fs=48kHz) parallel processing power. As the AK7735 is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects and proprietary high performance hands-free function. The AK7735 is available in a 48-pin LQFP package. 2. Features □ Dual DSP: (DSP1 and DSP2 have the same specification.
