I've been using TLV320AIC3111 EVM with codecontrol software. I am using the mic input as a line input with PGA set to 0dB and input impedance set to 20k (single ended). As soon as my signal amplitude crosses 25 to 30mV the ADC output becomes heavily distorted. The datasheet says that it can accept 0.707V(RMS). Is there some other gain register in the ADC path that I've to set to set so that gain of input signal chain becomes 0dB? Thanks.
