AK4618
192kHz 24-bit 6ch/12ch Audio CODEC with Microphone Interface
GENERAL DESCRIPTION
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.
