Other Parts Discussed in Thread: TLV320AIC3111
Hello,
I've been working on the design of a custom board based on the TLV320AIC3111 and am currently dealing with capacitor selection. I came to know of the piezoelectric effect also known as the ringing/singing capacitor effect that is exhibited in Class 2 and Class 3 MLCC capacitors like X5R and X7R and during the course of my research I've found many sources who recommend not to use Class 2, 3 capacitors in Audio Systems. However, looking at the reference for the TLV320AIC3111, it looks like all the capacitors used are Class 2 and 3 (X5R and X7R).
What kind of capacitors should be selected to minimize noise levels, considering that the audio we are taking as an input is very low intensity, and thus highly susceptible to noise?
