NEW AK7738VQ: Multi Core DSP with 5ch ADC, 4ch DAC, 8ch SRC

AK7738VQThe AK7738 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). Advanced 32-bit DAC’s are adopted for analog outputs, realizing a high-quality playback of high-resolution sound sources. The AK7738 is suitable for car audio, display audio, car navigation systems and hands-free systems.
