AK5736
Description
The AK5736 is a 6-channel ADC that supports line and microphone inputs with an SAR ADC for error detection. The error detection function monitors connection status of line and microphone inputs. The AK5736 has Pre-Gain Amplifiers (PGA) for microphone and Microphone bias (MIC bias) voltage sources. These functions make it ideal for microphone array applications such as automotive ANC, (Active Noise Cancelation), etc. The TDM audio format makes it easy to connect with a DSP.
