The LM108 series is a precision operational amplifier with specifications ten times better than FET amplifiers. It operates over a temperature range of -55°C to 125°C. The low current error of the LM108 series enables designs that are not practical with conventional amplifiers.
This document describes the LM108 series of precision operational amplifiers, which offer specifications a factor of ten better than FET amplifiers over a wide temperature range. The devices operate with supply voltages from 2V to 20V and feature sufficient supply rejection to allow the use of unregulated supplies. The series includes the LM108 (guaranteed from -55°C to +125°C), the LM208 (-25°C to +85°C), and the LM308 (0°C to +70°C).
