This is not a linear mode to have any difference on the inputs unless this is job for a comparator which is trivial to choose.However I know that voltage at noninverting and inverting input will be -10V and -12V respectively
Can the input voltage also go positive?make a circuit utilizing a quad single supply opamp which can handle negative input voltages at least up to -12V.
Hi Crutschow, Is not it true that MC34074 can operate with negative input voltages while in single supply mode without using offsets? Plz see attached datasheet. This is what it says on first page,No op amp will work with voltage at their inputs below the negative supply rail (0V here), but there are ways to handle negative signal voltages.
If you answer the questions in my previous post, I can better answer yours.
No both input will remain negativeCan the input voltage also go positive?
What is the full input voltage range?
What output do you want from the two inputs?
1) Differential, diagrams not drawn yetThrashing around w/o adequate description/design goals will not allow forum to help :
1) Single supply opamp configuration, Inverting, Non Inverting, Differential, what is it ?
Post a schematic.
2) For 1) what gain do you want ?
3) For 1) What is the input range V you want ?
4) For 1) and 2) what is output V you want ?
5) For 1) what is BW of signal
6) For 1) what is load on opamp ?
7) What is source of input signal, and its electrical description ? Z, range, BW....
YesSo for a -9 to -7 input differentially you want 0 to +5 output, just to confirm ?
Regards, Dana.
I can´t find any information that the MC34074 can handle negative input voltages with respect to it´s VEE.Is not it true that MC34074 can operate with negative input voltages while in single supply mode
--> Give your requirements as numbersis there any better opamp than LM324 in terms of better results
