Mic In amplification

Other Parts Discussed in Thread: TLV320AIC3100, CC2564

Hello!

I am using the TLV320AIC3100 audio codec along with the cc2564 BT module (they are connected with I2S while the cc2564 is the master).

is there a way to configure the TLV320AIC3100 so that it amplifies the mic in signal ? (i can hear the input from the mic but not as loud as i would like)

Thanks,

Hi, Yuri,

There are many ways to amplify the mic in signal. You may use Page 1 / Register 47 to modify the PGA gain and Page 0 / Registers 82-83 to increase the digital volume.
