These devices are low cost, high speed, JFET input operationalamplifiers with very low input offset voltage and guaranteedinput offset voltage drift. They require low supply currentyet maintain a large gain bandwidth product and fastslew rate. In addition, well matched high voltage JFET inputdevices provide very low input bias and offset currents. TheLF411 is pin compatible with the standard LM741 allowingdesigners to immediately upgrade the overall performance ofexisting designs.These amplifiers may be used in applications such as highspeed integrators, fast D/A converters, sample and hold circuitsand many other circuits requiring low input offset voltageand drift, low input bias current, high input impedance,high slew rate and wide bandwidth.Featuresn Internally trimmed offset voltage: 0.5 mV(max)n Input offset voltage drift: 10 μV/°C(max)n Low input bias current: 50 pAn Low input noise current:n Wide gain bandwidth: 3 MHz(min)n High slew rate: 10V/μs(min)n Low supply current: 1.8 mAn High input impedance: 1012Wn Low total harmonic distortion AV=10,RL=10k, VO=20 Vp-p, BW=20 Hz−20 kHz: <0.02%n Low 1/f noise corner: 50 Hzn Fast settling time to 0.01%: 2μs
