The data sheet for the TLV320AIC23B specifies an input signal level of 1 Vrms at 0 dB gain. What is the input signal level for the other gain stages? Can the input signal go higher when the gain is negative?

Hi Josh,
If the input voltage goes above the positive supply or bellow the negative supply (ground) you will activate the ESD protection diodes and risk damage to the part. Since 1 vrms is already 2.8 Vpp and the supply is 3.3, you should probably use an external divider to keep larger signals safely withing the operating range of the device.
