I'm doing more tests on the power supply since the first prototype board blew up number 1 pga2500. I think for some reason the power supply went higher that -5.5v on the negative supply. now the supply is just running three channels and i've been monitoring the voltages.
I get my Rigol DS2076A osciloscope tommorow, so looking forward to being able to check the power on too. Mainly checking all this before I start up the PCB version !! dont want to blow a pga2500 on one of the PCB's
I also need to wire up and test the Phantom48 switching IC before I add that to the PCB version.
