Signetics Integrated Circuits Operational Amplifier LM108 Series~Precision Operational CONNECTION DIAGRAM Amplifier N PACKAGE INTRODUCTION The LM108/108A series are precision cperational amplifiers having specifications a factor of ten better COMP) LI [2] come 2 than FET amplifiers over their operating temperature range. In addition to low input currents, these devices INVERTS EF Pv have extremely low offset voltage, making it possibie . in most cases, to eliminate offset adjustments.

The maximum junction temperature of the LM108/108A ve a re] NG is 150C, while that of the LM208/208A is 100C. For operating at elevated temperatures, devices in the TO-5 Unused pin ino internal connection) to aitow for package must be derated based on a thermal resistance input anti-leakage of 150C/W, junction to ambient, or 45C/W, junction : to case. The thermal resistance of the dual-in-line pack- - age is 100C/W, junction to ambient. REFERENCE TABLE 2. The inputs are shunted with back-to-back diodes for OUTLINE overvoitage protection. Therefore, excessive current will TYPE NO. STOCK NO DRWG. NO flow if a differential input voltage in excess of 1V is - _ applied between the inputs unless some limiting LM108F 55902C 1 resistance is used. LM108AF 559034, 1 3. For supply voltages less than +15V, the absolute maxi- LM108T 55904 x 7 mum input voltage is equal to the supply voltage. LM108AT 55905 7 4. The maximum junction temperature of the LM308 is LM308N 55906F 8 85C. For operation at elevated temperatures, devices LM308N-14 5907D 1 in the TO-5 package must be derated based on a LM308AN 559088 8 thermal resistance of 150C/W, junction to ambient, LM308AN-14 5909 X 1 or 45C/W, junction to case. The the-mal resistance of LM308T 55910C 7 the dual-in-line package is 100C/W, junction to LM308AT 559114 7 ambient. PLEASE QUOTE STOCK NO. AND MANUFACTURERS PART NO.
