Thank you for asking, James. Thought you had written me off as a waste of time.
TBH, I haven't tried your single ended amps, James. I don't want to run my galvos with a single-ended offset.
But, I'm using some of those components to prototype the breadboard for the PCB. I'm using the MD100 DC convertor to increase the power rails on the TL084 op amps from 0 & +5VDC to -/+9VDC to provide more gain and offset.
But whenever I add the smoothing caps to the MD100, it's output collapses and both overheat while under no load. Is this behavior only due to exceeding the capacitance of the load, which the datasheet says is a no-no? Do I simply need to add the caps after connecting the rest of the circuit?
The datasheet also recommends 5 uF across +5Vin & Gnd, instead of your 10uF. Was that additional capacitance just for good measure?
Thank you for your interest and assistance.
