AK5734 Datasheet (AKM) - 4-Channel Differential Audio ADC

AK5734, 4-Channel Differential Audio ADC

The AK5734 is a 4-channel audio ADC with an integrated SAR ADC, enabling robust error detection.

The error detection function monitors the connection status of the line and microphone inputs.

The AK5734 includes mic PGAs (pre-gain amplifiers) and programmable microphone bias.
