Description

The AK5734VN is a 4 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 AK5734VN has Pre-Gain Amplifiers (PGA) for microphone and Microphone bias (MIC bias) voltage sources.
The AK5734VN is these functions make it ideal for microphone array applications such as automotive Active Noise Cancellation (ANC), etc. The AK5734VN is TDM audio format makes it easy to connect with a DSP.

Applications

  •                                 Active Noise Cancellation systems (ANC), Road Noise Control system (RNC), Microphone modules, Automotive amplifier units, Automotive head units, car audio, Telematic Control Unit (TCU), etc.
