Hi!
I am facing some issues with OP4177 (precision amplifier) in a voltage limiting application. Earlier in the design LM-148 ( quad uA741) was used and there was absolutely no issue. In the same configuration OP4177 gives horrible results with absolutely…
After finding a couple of posts that address this question fairly well I am going to request that it be closed.

If an input exceeds the power supply rails on the OP4177, are there clamping diodes that will protect the device? If so, how much current is allowable?
Hi Mark,
all A and B terminals are directly connected to +2.5V or -2.5V. The W terminals are connected to the + terminals of an OP4177 operated by +/-12 V.
Hello everybody,
First of all, thank you for your replies, as this is my first post in this Comunity.
I have an Analog Input to measure the output signal (in current) of a HV transducer. The transducer is suplied to +- 24V
The Analog Input consists…
Datasheet is not complete clear to me.
Does this opamp only work with a negative voltage at v- or can it also work with 0 VDC at v- and 5 VDC at v+?
I am using an OP4177 in an externally powered application (voltage follower for battery cells). Is it OK to leave the voltage input from the cells connected when the supply power is off?
