Howdy
I am in the process of reviewing basics in OP AMPS, and i figured out that things doesn't seem to work as expected in SPICE simulators such as in Labcenter's PROTEUS.
But beyond such scope, i would like to know if i am correct in wiring the eponymous UA741 and LM301. Okay i know they're old, but i have to acknowledge they're great for learning. While QUAD op amps are good option as well. As mentioned in the heading, for now my need is just to do a 101 review.
How to properly balance the offset in 741 and 301?. Is such procedure of
grounding the terminals (inverting and non inverting) the most accurate or the most preferred?.
I checked the datasheets of both op amps.
But still clueless about it. Is that the correct way to do it?. I attached two images, the first one it is an example of the 741 configured as an inverting amplifier (with a gain of 10) using a 10k potentiometer as an offset. It seems to work more or less fine in PROTEUS. The second picture it is the same (741) as inverting amplifier, but configured to set up the offset balancing. THIS is the part i am not sure if i am doing correctly.
The same example is given with the 301, as an inverting amplifier and the second image is supposed to set it as offset balancing.
I would apreciate if anyone could give me a hand on this.
Cheers
