hi all,
how could I determine how many op amps I can run off the same power supply?
I am trying to find out how many opa548's i can run from a power supply that says it can deliver 5A max. here is the data sheet for the op amp https://www.electro-tech-online.com/custompdfs/2009/07/opa548.pdf

I am running some DC to HV-DC converters with these amplifiers, which take input voltage from a DAQ. someone mentioned that the power supply was limited to 5A, and that I should make sure that it would be able to run all 9 op-amps in the circuit at the same time. I don't know how many amps they need to draw from the power supply.
for my application the the converters draw about 1.5 amps, but I was hoping that on page 3 under power supply the listing of max Q current being +/- 20 mA would mean that I could run all nine. I wouldn't know how to even start dealing with the headache of switching between amps the whole time.
