DESCRIPTION The LM108/108A series are precision oper- ational amplifiers having specifications a factor of ten better than FET amplifiers over their operating temperature range. In addi- tion to low input currents, these devices have extremely low offset voltage, making it possible in most cases, to eliminate offset adjustments. The LH2108 series are hybrids featuring two LM108A type dice in the same hermetic package. The electrical parameters are the same as the single amplifier. 40 PIN CONFIGURATIONS LM108/A/208/A/308/A-F,N,N-14,T LH2108/A/2208/A/2308/A-F,N,N-14,T F PACKAGE we COMP 1 2] "GUARD BI INPUT *GUARD | 6 v- |?

DC ELECTRICAL CHARACTERISTICS Ta = 25C, 5V < Vs = +20V unless otherwise specified.1.2 The maximum junction temperature of the LM108/108A is 150C, white that of the LM208/208A is 100C. For operating at elevated temperatures, devices in the TO-5 package must be derated based on a thermal resistance of 150C/W, junction to ambient, or 45C/W, junction to case. The thermal resistance of the dual-in-line package is 100C/W, junction to ambient. . The inputs are shunted with back-to-back diodes fo- overvoltage protection. Therefore, excessive current will flow if a differential inpul voltage in excess of 1V is applied between the inputs unless some limiting resistance is used. . Forsupply voltages less than +15V, the absolute maximur input voltage is equal to the supply voltage. . The maximum junction temperature of the LM308 is 85C. For operation at elevated temperatures, devices in the TO-5 package must be derated based on a thermal resistance of 150 C/W, junction to ambient, or 45C, juriction to case. The thermal resistance of the dual-in-line package is 100C/W, junction to ambient.
