Other Parts Discussed in Thread: PCM2912A, TMS320C5533

Hi team,

My customer wants to use PCM2912A as pure Audio ADC to USB for USB MIC application.

Could our solution disable the DAC function to avoid the customer's end user to see the speaker out at UAC side?

Do we have the pure ADC to USB solution?

Thanks!

Best,

Jason

Hi Jason,

Unfortunately none of our USB codecs are able to disable the DAC.
We have USB codecs and DACs but there are no USB ADCs.
You could try to build a solution using an ADC from the TLV320ADC and another device that takes the I2S data into USB, perhaps something like TMS320C5533.
