Note 2:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits.
Note 3:
Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
Note 4:
Any of the amplifier outputs can be shorted to ground indefinitely, however, more than one should not be simultaneously shorted as the maximum junction
temperature will be exceeded.
Note 5:
For operating at elevated temperature, these devices must be derated based on a thermal resistance of
θ
jA
.
Note 6:
The LF147 is available in the military temperature range 55C

Note 8:
The input bias currents are junction leakage currents which approximately double for every 10C increase in the junction temperature, T
j
. Due to limited pro-
duction test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the ambient tem-
perature as a result of internal power dissipation, P

is the thermal resistance from junction to ambient. Use of a heat sink is recommended
if input bias current is to be kept to a minimum.
Note 9:
Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice from

Note 10:
Refer to RETS147X for LF147D and LF147J military specifications.
Note 11:
