LM124AQML-SP: Operational Amp, Pspice, Simulation

Part Number: LM124AQML-SP
Other Parts Discussed in Thread: LM124

Hello. I'm using LM124AQML-SP to simulate something in Pspice environment.

But i have some question about LM124AQML-SP...

Q1. when temperature has 0~60℃ range, it nearly doesn't affect to LM124AQML-SP's output voltage. Is it correct?

Q2. for LM124AQML-SP, there is no conception like initial tolerance. Is it also correct?

Best Regards.

    Hello Ahn,

    This is op amp, so the output voltage will mainly depend upon the input offset voltage and the external feedback circuit.

    The variation in input offset voltage is specified in the datasheet as +/-30 uV/C, so the LM124 should be responsible for very little shift in the output voltage over temperature especially at low gains.  The output voltage over temerature is more likely to be dependent upon the temperature coefficient of the external resistors in the application. 

    Let me know if you have any other questions, otherwise please mark this question as resolved.
