AK4617
192kHz 24-bit 2ch/12ch Audio CODEC
1. General Description
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.
