Please explain how to use OP90 as instrumentation amplifier as shown in figure 11 of it's datasheet Rev C.
This is a funky application where they use the Vos pins to unbalance the front end and then provide feedback on the other Vos pin.
I have an OP90 in an SOIC package. According to the Analog Devices Pin1 marking there should be a Dot to mark Pin1. Unfortunately this Dot is missing.
The branding and the missing dot or dimple looks different from standard ADI branding for SOIC8…
Please inform the OP90 Opamps replacement.
Thanks & regards
We are having difficulties obtaining this part. Do you have a 'drop-in' replacement for this part, with a similarly low input offset voltage, in a 8pin DIL package. We are using this amplifier in a battery powered, portable, analyser using…

Have a look at the OP90 or the OP193, both available as DIP parts. I would also say that prototyping with SO parts really isn't that hard, and I gave up on DIP many years ago.
