Replacement for 741

Sid 03 · 2021-01-19T17:59:12+00:00

I am looking for a drop-in replacement for 741, same ability without all the faults of the 741. Found a page that describes several replacements, but I am looking for a chip that will operate at 3 volts or below. Or is that asking too much ? The datasheet for TL071 showed the min V as 7v I couldn't find a min voltage for the OP27 What about the 'MCP6004' the data sheet that I found show it works with a supply voltage of 1.8 - 6v ? Has anyone of you ever used this chip or have another suggestion ? I like the low end of the voltage range but the high end could be higher. Thanks

The datasheet for TL071

I agree with George though--get some others as backup. I recommend LM319s. They're ten times slower than an LT1016 but ten times quicker than an LM393.

Worked for Fairchild in the daze when popcorn noise was a puzzler. I believe someone in National Semi solved it; basically a cleanliness issue.

RCA's second source part CA741 was available in a special low burst noise (aka popcorn) variant CA6741 circa 1972 which RCA claimed was made possible by their advanced process. Application note ICAN-6732 describes the test set.
