(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Refer to RETS442X for LF442MH military specifications.
(1) Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
(2) 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.

(1) Unless otherwise specified, the specifications apply over the full temperature range of VS = ±15 V for the LF442-MIL. VOS, IB, and IOS are measured at VCM = 0.
(2) Refer to RETS442X for LF442-MIL MH military specifications.
(3) The input bias currents are junction leakage currents which approximately double for every 10°C increase in the junction temperature, TJ. Due to limited production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the ambient temperature as a result of internal power dissipation, PD. TJ = TA + θJAPD where θJA 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.
(4) Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice from ±15 V to ±5 V for the LF442-MIL.

(3) The value given is in static air.
(4) These devices are available in both the commercial temperature range 0°C ≤ TA ≤ 70°C and the military temperature range −55°C ≤ TA ≤ 125°C. The temperature 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” indicates the military temperature range. The military temperature range is available in “H” package only.
