108/108A 208/208A 308/308A Precision Operational Amplifiers GENERAL DESCRIPTION The LM108A/LM108, LM2084/LM208 and LM308A/LM308 are Super Beta operational amplifiers fabricated on single silicon chips using the planar epitaxial process. The LM108A/LM108 offer specifications an order of magni- tude better than FET amplifiers over a temperature range 56C to +126C. The LM208A/LM208 are identical to the LM108A/LM108 ex- cept their performance is guaranteed from 25C to +85C, The LM308A/LM308 provide lower input offset voltage of 0.5mV maximum, and drift characteristics of 5.0uV/C maxi- mum. These devices can be compensated by the conventional technique used with the LM101/LM101A series.

Therefore, excessive current will flow if a differential input voltage in excess of 1V is applied between the inputs unless some limiting resistanc .
