AC Electrical Characteristics
Note 2: 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 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
Note 6: The LF147 is available in the military temperature range −55˚C≤T
range 0˚C≤T
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
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, P
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
V
Note 10: Refer to RETS147X for LF147D and LF147J military specifications.
Note 11: Max. Power Dissipation is defined by the package characteristics. Operating the part near the Max. Power Dissipation may cause the part to operate
outside guaranteed limits.
Note 12: Human body model, 1.5 kΩ in series with 100 pF.
