Tool/software:
We use pin14 & 16 as Mic signal input channels(other input channels are configured as not connected),
we found that when mic signal goes very much high, e.g. 3Vpp/1.07Vrms saw at the pin14 and then goes to left ADC, the right ADC pops out data even the pin16 is un-connected to external circuitry.
There's words describing not to exceed 2Vpp, but is this cross reaction between L and R, the consequence would occur?
As the Mic we use has internal amplifier and we currently has no schedule to implement AGC, would there be any method to avoid such phenomenon?
