Instrumentation, Op Amps, Buffer Amps FAQ

Does the LT1077 require external nulling?

While the device includes pins for offset adjustment, the extremely low inherent offset voltage makes external nulling unnecessary in most applications.

How does the LT1077 handle inputs below ground?

Internal series resistors protect the device from unlimited substrate current flow even if the input voltage drops up to 5V below the negative supply terminal.
