Hi all,
I have a couple of questions on Class-D amplifiers after I went through tons of pages here:
1. In full bridge configuration (single or dual supply), does it make any difference if the output low pass filter coil is wound on separate cores or single core?
2. Un-like in Class-AB, are Class-D amplifier immune to DC offset errors? There is little to no mention what so ever in any build threads of reference designs about it, both UCD and non-ucd type about need for DC servo or a dc servo improving quality parameters. If we compare half-bridge using dual supply vs full bridge using a single supply would there be any difference in any one faring better in dc offset error?
Thanks in advance!
