Hi Holger,

I think that you may be referring to PCM3052A.

Our Precision Op Amp Application team does not handle the support of this particular part.

Best,

Hi!

I think you could use an audio ADC like the TLV320ADC3101. I'm looping the DC-PADC team for additional details or other suggestions.

Holger,

The TLV320AIC3107 has a microphone amplifier, stereo ADCs (for the I2S output) and Stereo DACS (for the I2S input ) and a 1.8W amplifier.

There is also the TLV320AIC3100 or LM49352. If you only need the microphone amplifier but not the ADCs all of these still work.
