AK4586VQ

Audio Codec 2ADC / 6DAC 24Bit 44Pin LQFP

GENERAL DESCRIPTION

The AK4586 is a single chip CODEC that includes two channels of ADC and six channels of DAC. The

ADC outputs 24bit data and the DAC accepts up to 24bit input data. The ADC has the Enhanced Dual Bit architecture with wide dynamic range. The DAC introduces the new developed Advanced Multi-Bit architecture, and achieves wider dynamic range and lower outband noise.
