Any ideas why (no output load, just the two inductors & capacitors connected to pin 6 & 9 as per the datasheet)....
put the IC into standby (pin 11 low) ....IC cools rapidly, but out of standby the IC heat ups....I thought class D ICs were meant to run cool?
I'm using 33uh inductors & 0.1uf caps.
PS I don't have the 5-10R resistors on the output pins....as I think they are just there to present some resistance at high frequencies as this IC is meant for a piezo speaker.
An externally hosted image should be here but it was not working when we last tested it.
