We are evaluating TAS5414C-Q1 for automotive infotainment system. Below is the power supply schematic from TAS5414C datasheet. Is it low pass pi filter (clc)? If, yes what is the cutoff frequency?
Is it to prevent alternator noise from creeping into the audio signal? or to attenuate automotive power transients like load dump?
I have seen lot of reputed car stereos and amplifiers using 600uh -1 mh inductor and 3300uf capacitor forming low pass LC filter at power input to the system. This one is quite different. Any specific reason?
