Part Number: TPA2038D1
Hi allWould you mind if we ask TPA2038D1?Input coupling capacitor(AC coupling) on TPA2038D1YFFEVM is 0.1uF.In case of AV = 6 dB : the cutoff frequency will be 21.2HzIn case of AV = 12 dB : the cutoff frequency will be 10.6HzIn generally, we guess that the big capacitance value will be cause of pop-noise.So, in case of using 0.1uF, as your experience, is it no level which you worry pop-noise?If you have some advice, please let us.Kind regards,Hirotaka Matsumoto
In reply to José Luis:
I am using TPA2038D1 audio amplifier part in my design. I have used 0.1uf capacitor in unbalanced input mode. I have pop sound issues at both start and end of the audio file play. can you please help me to solve this issue?. When audio file is played, Line voltage raised to 3.3V from 2.2 V . Also when audio play stopped line voltage is dipped to 0V from 2.2V.
