The AK4618 is a single chip audio CODEC that includes 6-channel ADC and 12-channel DAC. The 6-channel 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 AK4618. The AK4618 is housed in a space saving 48-pin LQFP package.
