Operating ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. (3) Refer to RETS444X for LF444MD military specifications. (4) Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage. (5) 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. (6) For operating at elevated temperature, these devices must be derated based on a thermal resistance of θjA. (7) Max. Power Dissipation is defined by the package characteristics. Operating the part near the Max. Power Dissipation may cause the part to operate outside ensured limits. (8) The LF444A is available in both the commercial temperature range 0°C ≤ TA ≤ 70°C and the military temperature range −55°C ≤ TA ≤ 125°C. The LF444 is available in the commercial temperature range only. 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 “NAK” package only.

VOS, IB, and IOS are measured at VCM = 0. (2) 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. 2 Submit Documentation Feedback Copyright © 1998–2013, Texas Instruments Incorporated Product Folder Links: LF444 |
