TLV320AIC3206: Routing signal through AGC

Kristian Solberg
Prodigy 30 points

Part Number: TLV320AIC3206

Hi.

I have a project where I'm using an external AGC before the TLV320 chip.

But I was thinking maybe I could simplify the design by using the built in AGC.

The problem is that I'm doing analogue signal processing after the AGC.

So the question is. Can I route the signal through the fist AGC then out on the line out, through the analogue circuit, and then back in on the second channel? 

Can I do this while also using one mono i2s MEMS microphone?

    Hi, Kristian,

    The routing you are showing is actually possible for the application you are describing. One thing to note is that you mentioned you are using an I²S mic, if that is the case you need to use the I²S port of the device to capture the data, not the Digital mic interface.
