Look at ADA4077-2 or ADA4522-2.
The data sheet and reference designs recommend the AD8676 for voltage reference buffers. I would like to use an opamp that draws less supply current than the 3.4mA max of the AD8676. The ADA4077-2 looks to have similar performance specs, and draws only…
The OP2177 is junction isolated on P-type starting material so the V- pin is the substrate.
You should apply V-, then V+.
For shut down, remove V+, then V-.
Also note the ADA4077-2 is a next generation version of the OP2177.
I want you to give us advice.
OP2177 is targetted to be replaced with competitors, OPA2180 and so on.
We try to promote ADA4077-2A. But they mentioned TCVos is worse than OP2177. They don't want to use it.
ADA4522-2 doen't seem to compete…
I would not do a new design with the OP2177. The next generation part, the ADA4077-2, is now released.
Take a look.
