Overview
[AK4618] 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.
