TLV320AIC3268: Microphone Input ADC Oversampling

MattLin

Part Number: TLV320AIC3268

Hi Team,

I have a customer trying to configure the Microphone input to be optimized for maximum frequency bandwidth (up to 22 KHz).

Are there also ADC oversampling filters etc that we should be looking at to enable this properly?

Thanks,

Matt

Hi Matt,

Hi Matt,

The 22 kHz pass-band requirement can be achieved by using PRB_R1 miniDSP_A mode at 96 kHz sample-rate.

The device configuration to generate this response is attached. The frequency response measurements are also attached.

Best Regards.
