It requires low supply current, yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset currents. The LF411 can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits. The LF411C is characterized for operation from 0°C to 70°C. The LF411I is characterized for operation from –40°C to 85°C. symbol IN – IN + BAL1 BAL2 2 – 3 6 OUT + 1 5 AVAILABLE OPTIONS TA VIOmax AT 25°C 0°C to 70°C –40°C to 85°C PACKAGE SMALL OUTLINE (D) PLASTIC DIP (P) 2 mV LF411CD LF411CP 2 mV LF411ID LF411IP The D packages are available taped and reeled.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
