Sampling simultaneously 8 analog microphones with ADC120

[Levan]

Hi All,

Could you please advice. Does ADC120 support simultaneous sampling of 8 channels? Can i connect to it 8 IMP23ABSU Analogue MEMS microphones, sample acoustic signals from all microphones for further processing in DSP?

Simultaneously, no.

This is a single ADC with 8 channels, only one channel can be sampled at a time.

Hello @Levan 

ADC120 use an 8 to 1 multiplexer. That's why he can convert only one channel a time.

Best regards.
