• Description: Dual Low Power JFET Input Operational Amplifier
• Manufacturer: National Semiconductor

AC Electrical Characteristics
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
Note 3: 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 4: The value given is in 400 linear feet/min air flow.
Note 5: The value given is in static air.
Note 6: These devices are available in both the commercial temperature range 0˚C
perature range is designated by the position just before the package type in the device number. A “C” indicates the commercial temperature range and an “M” indi-
cates the military temperature range. The military temperature range is available in “H” package only.
Note 7: Unless otherwise specified, the specifications apply over the full temperature range and for V
V
Note 8: The input bias currents are junction leakage currents which approximately double for every 10˚C increase in the junction temperature, T
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
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 RETS442X for LF442MH military specifications.
