Note 1
The maximum junction temperature of the LM108A is 150 C while that of the LM208A is 100 C For operating at elevated temperatures devices in the H08
package must be derated based on a thermal resistance of 160 C W junction to ambient or 20 C W junction to case The thermal resistance of the dual-in-line
package is 100 C W junction to ambient
Note 2
The inputs are shunted with back-to-back diodes for overvoltage protection Therefore excessive current will flow if a differential input voltage in excess of
1V is applied between the inputs unless some limiting resistance is used
Note 3
For supply voltages less than
g
15V the absolute maximum input voltage is equal to the supply voltage
