97dB/106dB 192kHz 24-Bit 2ch ADC & 12ch DAC

  • Inquiry
  • Evaluation Board Manual
  • Data Sheet


The AK4617 is a single chip audio CODEC that includes 2-channel ADC and 12-channel DAC. The stereo ADC supports differential/single-ended analog inputs. The high performance 12-channel DAC integrates full-range digital volume control and achieves 106dB dynamic range. A car audio system can be easily designed with an audio DSP and the AK4617. The AK4617 is housed in a space saving 48-pin LQFP package.
