I am using TLV320DAC3100 Audio amplifier IC. According to the datasheet the speaker output signals SPKM & SPKP are Inverting and Non-Inverting signals .But I got below waveform when SPKM and SPKP signals are probed.
Is this is the expected waveform or I am getting wrong waveform?. Can you please provide the expected speaker output waveform.
Also I have one more query.
I am hearing hissing sound while audio is playing. whether I need to add any external filter to reduce this noise. Please suggest.
