TLV320ADC3101-Q1: MUX between analog and digital inputs

Angeline Previtali

Part Number: TLV320ADC3101-Q1

Hello,

I was thinking of using the component TLV320ADC3101-Q1 to interface two digital (in PDM) and one analog microphones. I want to communicate with my CPU in TDM. In my application the digital and analog microphones do not work simultaneously. I would like to know if it is possible to have a TDM2 output (and not TDM3 since I only use two microphones simultaneously).

My question might not be clear, don't hesitate to ask for clarification if you don't understand.

Thanks for your help !

    Hi, Angeline,

    The ADC3101 is capable of streaming two channels of TDM data, which can be selected from either analog source or digital mic. The selection is done with registers configuration.
