AK4601
Audio HUB CODEC with Digital Mixer
1. General Description
The AK4601 is an Audio HUB CODEC including 5ch ADC, 6ch DAC and digital mixers. The analog input
block consists of a 24-bit stereo ADC, a 24-bit stereo ADC with input selector and a monaural ADC, and
the analog output block consists of 32-bit 6ch DAC. The transfer block for digital signals integrates a
serial interface that supports Data BUS and TDM format, realizing an audio HUB function. It gives
scalability to the device for both analog and digital signals.
A car audio system that is capable of processing both sound and voice such as for hands-free function
simultaneously can be realized by using the AK4601 with AKM’s multi-core DSP, the AK7707. The
AK4601 is available in a space saving 48-pin LQFP package.
