Supply = 12 or 15V

10kHz bandwidth would suffice !

Will only be used as a voltage follower

I/P and O/P must go to GND ( V+ not such an issue )

I input bias uncritical, i.e. bipolar fine. Source Z < 2k

Vos < 3 mV would be fine

Must be through hole ( ideally )

Suggestions ? Not my normal area !

Criteria include low cost, multiple sourcing and good stock levels


Thanks, Graham

Check the TLC2272.

LM6132 is a dippie, nice R-R I/O (actually, a bit outside the rails on
inputs, output not quite there for largish loads), not quite your Vos
spec at guaranteed max, and maybe little tight on phase margin (though
it is spec'd for unity gain applications).
