I just hooked LM358 Op Amp, and I not getting the voltage I am expected at the output.
It is connected as follows:
-The supply voltage is 5V
-There is 330 Ohm between 5VDC and the inverting input.
-There is negative feedback resistor of 1K (between inverting input and output)
-The noninverting input is ground.
-The LM358 does not have/need negative supply.
Now, simple Ohms law tells me:
The current through the 330 is 5/330 = .015A
So, the current through 1K = -.015A
The output should be Vout = (-.015) * 1000 = -15VDC
But when I measure it, it is equal to 0.816VDC
I can't figure out why. Shouldn't it be around 5VDC (the maximum it could go)
This LM358 is brand new.
Thanks.
