Note 1:
The maximum junction temperature of the LM321A is 85
§
C. For operating at elevated temperature, devices in the H08 package must be derated based on
a thermal resistance of 150
§
C/W, junction to ambient, or 18
§
C/W, junction to case.
Note 2:
The inputs are shunted with back-to-back diodes in series with a 500
X
resistor for overvoltage protection. Therefore, excessive current will flow if a
differential input voltage in excess of 1V is applied between the inputs.
Note 3:
For supply voltages less than
g
15V, the absolute maximum input voltage is equal to the supply voltage.
