My First OP-AMP Circuit

3 09 2011

My Glassman high voltage power supply can be controlled with a 0-10VDC signal.

But most computer interfaces (like the arduino ) output 0-5VDC.

So today I built my first OP-AMP circuit to double a DC voltage:

I found a LM358M operation amplifier laying around.

Now I have a 2X voltage doubler! Sweet:

Was going to say I hope that is a rail to rail op-amp. But your multimeter shows that to be the case.

Love the harmonica there with your stuff…

[…] we just add the voltage doubling op-amp circuit I made previously, and […]
