LF411CN Description

LF411CN JFET input operational amplifiers are low-cost, high-speed devices with very low input offset voltage and input offset voltage drift. They have a low supply current requirement while still having a big gain bandwidth product and a quick slew rate. Furthermore, well-matched high voltage JFET input devices have extremely low input bias and offset currents. The LF411CN is pin compatible with the LM741, allowing designers to improve the overall performance of current systems right away. These amplifiers can be utilized in high-speed integrators, rapid D/A converters, sample-and-hold circuits, and a variety of other circuits that require low input offset voltage and drift, low input bias current, high input impedance, high slew rate, and wide bandwidth.
