TL062 vs OPA2137

[spoontex]

Hi,

I've found in box some OPA2137. I can substitute the TL062 with this OPA2137? Worth it?

Thanks.

At a quick glance it looks like a "slightly better" version than the 062 .. but not by much. Most likely it would work in most circuits designed for a 062.

Great, thanks!!

The TL062 is the same circuit topology as the TL072 but optimized for low current drain.  Some people like it for tremolo / vibrato / phaser oscillators to avoid the tick that comes from power switching.  But the TL062 has a high input noise, 40 nV/root Hz rather than the TL072's 18 nV/root Hz which makes it less suitable as a linear amplifier.  The OPA2137 has a higher input noise, 45 nV/root Hz so a TL062 might be a slight improvement over it.

Many thanks.

It's for an easy vibe build. I think that I mount the tl062.

In a low-gain circuit, this may not make any meaningful difference.
... but you wouldn't use a 062 in a high-gain cckt anyway, would you.
