11 / 21 page LF411-N www.ti.com SNOSBH6E – APRIL 1998 – REVISED OCTOBER 2014 7 Detailed Description 7.1 Overview These devices are low-cost, high-speed, JFET input operational amplifiers with very low input offset voltage and input offset voltage drift. They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF411 is pin compatible with the standard LM741 allowing designers to immediately upgrade the overall performance of existing designs. These amplifiers may be used in applications such as high speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage and drift, low input bias current, high input impedance, high slew rate and wide bandwidth. 7.2 Functional Block Diagram 7.3 Feature Description The amplifier's differential inputs consist of a non-inverting input (+IN) and an inverting input (-IN). The amplifier amplifies only the difference in voltage between the two inputs, which is called the differential input voltage. The output voltage of the op-amp VOUT is given by the equation VOUT = AOL(IN+ - IN-). 7.4 Device Functional Modes 7.4.1 Simplified Schematic Figure 27.
