Instrumentation, Op Amps, Buffer Amps FAQ

How does the common-mode input voltage range behave relative to the supply rails?

The common-mode input voltage range extends below the negative rail, allowing the device to accept signals down to -0.2V even in single-supply configurations.

What is the mechanism for external input offset nulling?

External input offset nulling is achieved by connecting a potentiometer between the dedicated offset control pins (N1 and N2) with the wiper connected as specified in the datasheet application notes.
