Micro Amp at 18volts. Understanding the IC differences? Really wanna learn...

[sevenisthenumber]

I built a Micro Amp up and originally used a tlo71 as the ic. When i ran 18 volts it wouldnt work. I swapped the chip out for a lm741 and it works great at 9 or 18. Can someone teach me why this is?
Thanks

There shouldn't be a problem with running a TL071 at 18V. It is rated for +/- 18V supply voltage and if you are running it on 18V, you are only giving it half of that. Maybe yours is defective.

hmmm... i tried several.

Bad batch?
Where did you get the 071's from?

BTW, sevenisthenumber: You are officially a Timer IC with your 555th post
