Note 1:
The maximum junction temperature of the LM102 is 150
§
C, while that of the LM302 is 85
§
C. For operating at elevated temperatures, devices in the H08
package must be derated based on a thermal resistance of 150
§
C/W, junction to ambient, or 20
§
C/W, junction to case.
Note 2:
For supply voltages less than
g
15V, the absolute maximum input voltage is equal to the supply voltage.
Note 3:
It is necessary to insert a resistor (at least 5k and preferably 10k) in series with the input pin when the amplifier is driven from low impedance sources to
prevent damage when the output is shorted and to ensure stability.

Note 5:
Increased output swing under load can be obtained by connecting an external resistor between the booster and V

terminals. See curve.
Note 6:
Refer to RETS102X for the LM102H military specifications.
APPLICATION HINT
The input must be driven from a source impedance of typically 10 k
X
(5 k
X
Min) to maintain stability. The total source
impedance will be reduced at high frequencies if there is stray capacitance at the input pin. In these cases, a 10 k
X
resistor
should be inserted in series with the input, physically close to the input pin to minimize the stray capacitance and prevent
oscillation.
