TLV320AIC1103: Maximum input and output signal amplitude

Part Number: TLV320AIC1103
Other Parts Discussed in Thread: TLV320AIC3104, TLV320AIC1106

Hello support team,

I have some questions about TLV320AIC1103.

The customer's terms of use are as follows.
Power supply: 3 V
Analog input signal: single end 1 channel (MIC 1 P: fixed, MIC 1 N: analog input)
Analog output signal: single end 1 channel (EAR 2 O)


(1) Is the maximum single-end input amplitude that can be input to each terminals of MIC1P, MIC1N, MIC2P and MIC2N 124 mVpp?
I think so because specification value of "Overload-signal level (3 dBm0)" on page 9 of the data sheet is 248 mVpp (differential). Is my understanding correct?

(2) What is the maximum single-end output amplitude that can be output from each terminals of EAR1OP, EAR1ON and EAR2O?
Regarding EAR1OP and EARON, I think their amplitude are 2.47 Vpp as calculated result, because specification value of "Earphone AMP 1 output power (32 Ω load, 3 dBm0 output)" on page 8 of the data sheet is 95.1 mW.
And regarding EAR2O, I think its amplitude is 1.79 Vpp because specification value of "Earphone AMP 2 output power (32 Ω load, 3 dBm0 output)" is 12.5 mW.

(3) What is the dynamic range (maximum allowable amplitude) of each blocks of "TX Filter and PGA", "RX Volume Control" and "RX Filter and PGA"? The customer wants to know wheather the signal comes to saturate or not if he increases the gain of these block.

(4) What is the signal amplitude in mVpp for 1 LSB in case that the power supply voltage is 3 V and the operation is at in Linear mode?
