    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
     
  2. 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).
