The question is theoretically does anyone know of a situation where increasing the resistance of the load on an op amp would lower the gain. In theory, it should require less current.
I do not believe that more information is required to answer. If you do not have an idea for an answer, you...
There is no need to be so snarky. Here is a schematic of my circuit. The problem is that increasing the resistance of the load is causing the gain to fall to basically unity, not that the circuit does not function at all. It functions fine in exactly the same conditions with a smaller load. To...
Hi,
I am using an Apex PA443DF operational amplifier to drive a sinusoidal signal at 100 V amplitude across a very large resistor with resistance of about 5000 Mega ohms. The amplifiers are set up as noninverting with a gain of 22 and function very well for small resistive loads. The sinusoids...
