This document describes the LM216, LM316, LM216A, and LM316A operational amplifiers, which are precision devices designed for applications requiring extremely low input current errors. They utilize supergain transistors in a Darlington input stage to achieve input bias currents comparable to high-quality FET amplifiers, even in limited temperature ranges. These devices are internally frequency compensated and include provisions for offset balancing with a single external potentiometer. A key feature is the protection of the MOS compensation capacitor against catastrophic failure from overvoltage spikes on the supplies.
