quad opamp, isolation amplifier

1.can any one tell me which is the better one. LM124 or OP467?or any other quad opamp?

2. can any body suggest a replacement for ISO120 isolation amplifier?

    Hi renj,

    We have a couple of military-grade quad amplifiers in our portfolio. Apart from the OP467, I would recommend that you take a look at the AD704. It has higher precision (low offset, very low bias current) and I believe it also has enough bandwidth and slew rate if I'm going to compare to the amplifier you were previously using. The OP467 does not have as low an offset and bias current as the AD704, but it does have a much higher bandwidth at 21MHz and slew rate of 125V/us. Your choice will ultimately depend on the requirement of your application.

    I believe we have a military grade isolation amplifier, the AD203. However, I am not an expert on this product so I cannot comment on how it compares. For this part, I recommend that you contact your local ADI technical support for more information:

    I hope this helps!

    Thanks,
