Description

The AK7735EQ 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 3072 step/fs (when fs = 48kHz) parallel processing power. As the AK7735EQ is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects and proprietary high performance hands-free function. The AK7735EQ is available in a 48-pin LQFP package.

Key Features

  • Data width | 28-bit (abbreviated floating point supported)
  • Machine cycle | Fastest 6.8ns (3072 fs, fs = 48kHz)
  • ALU | 52-bit arithmetic operation (with 4-bit overflow margin)

Applications

  •                                 Digital audio equipment. etc.
