Ive ordered a cheap function generator from the internet . It requires both 12 and -12 power rails.
I also have a variable Buck power supply, I was planning on tuning it to 24v using a voltage divider with two resistors to achieve the power rails.
I have seen that an OP AMP draws (dependent on the output) around 4-5mA max on each rail.
I was just questioning whether this setup would work without complications? I was thinking of using 2 1k resistors to achieve 12v to use for the reference.
Here is is the function generator ( I am assming it uses a R2R resistor + summing OPAMP as they usually do). Function Generator
Thank you for your time!
