Electrical Characteristics
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
differential input voltage in excess of 1V is applied between the inputs
Note 3 For supply voltages less than
Note 4 These specifications apply for
specifications are limited to
Note 5 External precision resistor
Note 6 See RETS121X for LM121H 883 military specs and RET121AX for LM121AH 883 military specs
