Description

The AK7738AVQ is an audio/voice digital signal processor that realizes high performance hands-free voice process in addition to audio process. Surround sound processing and high performance noise and echo cancellations can be executed simultaneously by the Multi Core DSP (Digital Signal Processor). This device integrates two stereo ADC’s (A/D converter), one monaural ADC, two stereo DAC’s (D/A converter) and four asynchronous SRC’s (Sample Rate Converter). The AK7738AVQ is advanced 32-bit DAC’s are adopted for analog outputs, realizing a high-quality playback of high-resolution sound sources.

Applications

  •                                 Car audio, display audio, car navigation systems and hands-free systems. etc.
