Instrumentation, Op Amps, Buffer Amps FAQ

How does the frequency response behave?

The op amp is internally compensated for gains equal to or higher than three. Frequency response can be optimized using an external compensation capacitor.

What is the maximum differential input voltage?

The maximum differential input voltage is limited to ±0.5 V. Diodes protect the inputs against overvoltage, but large currents may flow if this limit is exceeded without current-limiting resistors.
