Hi, Gurus,
I need a MIC DRC preamplifer.
But I found it is difficult.
1. My MIC is diff in and diff out, so many DRC preamplifer of AD isn't fit for.
2. The preamplifer is linked to ADC, so TPA2017 can be used, but it seems class-D is more than enough.
And TPA2017 is dual MIC amplifier, my module has only one MIC. And I have to found another audio amplifier for earpiece. I wonder if another path can be used for earpiece diff path?
Who can recommend me a suitable audio MIC IC?
It supposed have:
MIC diff-in and diff out
ONE MIC amplifer
and one amplifier for earpiece?
Many thanks.
Tony Liu
