These devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and guaranteed 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.

Features

Internally trimmed offset voltage:	0.5 mV(max)
Input offset voltage drift:	10 µV/°C(max)
Low input bias current:	50 pA
Low input noise current:	0.01 pA/SqrtHz
Wide gain bandwidth:	3 MHz(min)
High slew rate:	10V/µs(min)
Low supply current:	1.8 mA
High input impedance:	10¹²
Low total harmonic distortion:	<=0.02%
Low 1/f noise corner:	50 Hz
Fast settling time to 0.01%:	2 µs
