| Dec 26, 2022 at 9:48 | comment | added | Circuit fantasist | @Russell McMahon, I (and not only me, I guess) am happy to have such wonderful people as you as moderators here. You are a great team. At the end of the current year, I want to thank you for your invaluable help and apologize for the (occasional) inconvenience caused. Happy New Year! | |
| Dec 26, 2022 at 9:34 | comment | added | Russell McMahon♦ | @Circuitfantasist Yes. I was just noting that your response above indicated that you MAY have just seen my comment from 7 years ago :-). As happens. At the time I was not a moderator so I wrote and answer based on your deleted answer and attributing it, so that your input would "live on". | |
| Dec 26, 2022 at 9:32 | comment | added | Circuit fantasist | @Russell McMahon, Yes... but the question is still relevant, isn't it:-)? | |
| Dec 26, 2022 at 9:27 | comment | added | Russell McMahon♦ | @Circuitfantasist I posted that reworking just under 7 years ago :-) | |

Added answer about the OP's circuit
|
| Dec 25, 2022 at 19:55 | comment | added | Circuit fantasist | @Russell McMahon, Thanks (better late than never:-) It would be interesting to show how this "potmeter" symmetrizes the op-amp (internal structure)... | |

| Dec 25, 2022 at 18:47 | comment | added | Circuit fantasist | @Scott Seidman, I hasten to ask you before the New Year has come again :-) What did you not like in my explanation back then, 8 years ago? | |

| Jan 1, 2015 at 15:00 | comment | added | Circuit fantasist | @Scott Seidman, I have decided to start the new year by a fancy story about the evolution of the op-amp differential amplifier. BTW, as drawn, the AD circuit diagram is more appropriate for the intuitive understanding... | |

| Dec 31, 2014 at 20:13 | comment | added | Scott Seidman | Happy New Year!! | |
| Dec 31, 2014 at 19:34 | comment | added | Circuit fantasist | Well, I will consider it... but now I have to go back to the New Year's table... the New Year comes here after three hours... Cheers! | |
| Dec 31, 2014 at 18:44 | comment | added | Scott Seidman | This doesn't seem right, given the circuit from the AD handbook I put up. | |
