Update:
I have finally received my new MAX038 IC and guess what?
It works like a charm!!
I'm so happy that I no longer need to get frustrated on finding the problem; just a faulty component ;)
thanks for all your help!
There is still some noise on the signal, but that's probably because I...
Ok. Thanks for all the help.
I'm going to buy a new MAX038 IC.
There are 5V regulators just before the MAX038 so I think it's 100% safe for the new IC?
Is there any chance the circuit causes the MAX038 to be destroyed?
I don't want the IC to also go broken from the moment I plug it in.
Hello,
I was wondering if it would work to make a +-5V supply, using a >10V DC supply:

It would be used to power ICs.
Kind regards
well I'm thinking it is normal for the V+ to get overloaded.
When the V- side gets loaded too much, the opamps output will be pulled towards V-, which automatically increases the voltage from output to V+, since the total voltage must always be 30V.
Supply voltage is 29V
V+ = +25V and V- =...
ah I see. But without the MAX038 connected, the capacitors don't give a problem, and with resistors connected,
giving the same load as the MAX038, also no problem, so I think I should search in another direction?
I really don't understand how it's possible for the OpAmps output to be giving a...
Is it possible that the OpAmp can't deliver enough current to the MAX038?
OpAmp can deliver 60mA, MAX038 I+ is 35mA, V- is 45mA.
I'm not sure how to calculate what current will flow trough the OpAmps output, since the positive voltages is sinked and the negative is sourced, right?
Do I have to...
Hello,
I tried to make a simple function generator using the MAX038 IC.
Schematic: https://www.circuitlab.com/circuit/mx397v/max038-function-generator
the OpAmp is a LT1364.
When the MAX038 is NOT connected yet, I'm getting + and - 15V, as expected.
For what should be + and - 5V, I'm...
