Recently, i bought LME49720HA n i want to bias this chip become class a (on my desktop cmoy), do i need put resistor or diode? if resistor, the value?(my PS is running DC+-18 volt)
Class A operation requires knowing the load current - so what headphones?
then you can assume a max SPL and calculate the current required by that load
"CMOY" doesn't seem to have any real meaning here any more - can you point to the schematic, identify the rail splitter, its current capability?
