Hi,
For the differential inputs, the input signal level is mentioned in TLV320AIC3204 data sheet as below however it seems that the unit is incorrect.
So, is my understanding correct that the unit is not mV but mVrms ?
In addition, is the analog full scale input voltage 1Vrms for the differential inputs if the channel gain setting is 0dB ?
Best regards,
Kato
Hi, Kato-san,
Correct, the unit should be mVrms. The differential input voltage to get 0dBFS digital output is a 1 Vrms when CM=0.9V.
