TL062 replacement recommendation

elseif · 1st August 2008, 08:57 PM

Electric bass preamp.

TL062 is a dual, DIP-8 pkg.
Iq <= 500 uA/section approx
en <= 40 nV/rt-hz

I can make a SOIC-8 package fit if I have to.

NE5532, TL082, TL072... use google, read datasheet and choose.

Pretty well all drop-in substitutions will draw more current. If, as I suspect, this is an onboard preamp substitution will cost battery life.

TH.J.B · 2nd August 2008, 02:34 PM

For onboard preamp FET amplifier would be better choice than op-amp, but I guess it doesn't satisfy you at all. Low noise and low current, look at analog devices op-amps like OP297, but it has very low slew rate.

BTW: what was the question? Now I'm a bit confused... are you looking for substitusion?

Peace!

if this is a line powered unit, TL072,TL082, LF353, or any standard dual op amp will work. if it's battery powered, you will want to find a low power op amp as a replacement. TL062's are a very common item, and most suppliers should carry them (and they should be relatively cheap).

Power it offboard. Do not limit yourself to battery power.

I usually thought of the TL072 as a reasonably low current device, I wouldn't think you'll lose that much battery life (or to a point that it becomes an excessive use of batteries).

Also an option...

Hi,

The TL072 is an allegedly identical but selected TL062.

Sorry for not including the reason for wanting the replacement suggestion. This is a 9V battery powered, bass guitar on-board preamp and it is noisy. It is a typical three-band fixed tuned unit with two stages.

Looking at the offerings from Linear Tech and Analog Devices, it appears that low noise and low current consumption do not go together too well.

Choice is limited due to supply. Do you mean noise as in hiss ? If you remove C2 does the noise go ? A TLO62 shouldn't be that noisy -- true it's not the ultimate but noisy -no.
