Original question:

LM741QML: AD741SH replacement

LM741: CMRR Changes with Frequency

Mike Woodard
Prodigy 245 points

Part Number: LM741

Are there any graphs available that address how the CMRR varies over frequency for the LM741, LM741MIL, or LM741QML, etc.? Also, if a parameter on the LM741 datasheet is not covered on the LM741QML can the value on the LM741 datasheet be used when comparing the LM741QML with other op amps?

    Hi Mike,

    Unfortunately, I cannot find any typical curves for the LM741 datasheet. The commercial vs. military grade LM741 device have differences in packaging, bill of materials (BOM), and testing which can all contribute to specification differences, so while using the commercial datasheet can offer a general idea of the op amp behavior, there can be differences in the specifications. Is there are particular specification you are looking at?

    Best,
