Part Number: TPA3110D2

measure the signal in DRV602PWR+PA3110D2, the TPA3110D2PWP voltage is -0.7V.

Questions:

Why TPA3110D2PWPR has voltage level under "0"
will it make speaker distoration, if the TPA3110D2PWPR has voltage level under "0" voltage
is there any way to force LINP input level boot up above "0V"?

add two question,
4. what does LINP input voltage specification of amplitude and DC limite?

5. we use speaker impedance is 5.6 ohm, when TPA3110D2PWPR input signal 2Vp-p and gain setting 26dB, the output current waveform has been distorted, which is normal?

4 Is there any voltage limitation in LINP input?
5. customer drive 5.6ohm speaker by TPA3110D2. the current signal for TPA3110D2 is input 2Vp-p(CH4), and configure 26dB gain and TPA3110D2 found distortion in its output current in CH1. Is that the normal in TPA3110D2?
