TL072IP ?

[lowstar]

hi everybody,

i always thought that the tl072ip is the low noise version of the tl072 chip (as stated on the banzai website, and somewhere here on this forum in a thread ´bout tube screamers i think).
some time ago, i got two of them. today, i played around with the la-light and tried different op-amps since it has some hiss.
couldn´t hear any difference.

googled up the datasheet...
...

the c suffix is for temp from 0 to 70 degrees celsius
the i suffix is for temp from -55 to 85 degrees celsius

and the p is just the package suffix.

oh wow.
so the low noise thingy is just a web legend it seems.

cheers,
lowstar

The noise thing is 72, 62, 82.  That is where you find the lower and higher noise versions.

In what order?

You mean you busted a "legend" with some basic research that the average pedal user would not do ? I'm shocked. I guess we can tell these guys to stop working:



Good job BTW.

Looks to be (lowest to highest) TL82, 72, 62.  Usually the higher the current the lower the noise, and the 82 uses the most current.
