If you run the op-amp off a 0V and 5V from a power supply, for instance, and then connect those two places I mentioned to the 0V of the same, it will not work. Instead, you have to connect those two places to somewhere halfway between the …
How to Build a Dual Polarity Power Supply Circuit In this project, we will show how to build a dual polarity power supply circuit with a DC power supply. In this circuit, we are not building a power supply from scratch. …
So pretty much I have a ~4.5V power supply from 3 AA batteries, that I want to power an op amp (LM358P). The reason I''m doing this is so I can boost the AC signal from a piezo sensor, the problem is, every time I set it up correctly (I think), without the signal inputs, it gets really hot, I''ve read the data sheet and kinda get whats going on.
Introduction to Dual Op Amp IC LM358 LM358 IC is a dual operational amplifier integrated circuit with two Op-Amp powered by a common power supply. It consists of two independent compensated …

I tried to find on the web distributors some IC that provide a dual ±2.5V power supply from a single positive source, but I found one or two solutions that don''t satisfy me at all. Furthermore, these IC use a charge pump that create on the output a very high ripple, but I think that if I use two LDO regulator with high PSRR the problem is in …
I was buildiing an amplifier circuit for +ve voltages only. When I used a 9V battery to supply V+ and V- (+ to V+, - to V-), I get a constant 8V at the output of the opamp. The output is not changing According to page 4 of the LM741 datasheet, the minimum supply voltage is +/- 10V, so powering it with +/-9V isn''t guaranteed to work.
Regarding power: the easiest way to power the circuit is with 2 9V batteries. To feed your op-amps -9V to 9V of power, connect one battery the correct way, and one backwards. That is, connect the positive lead of one battery to your positive power supply line
