LF411 Low Offset, Low Drift
JFET Input Operational Amplifier
General Description
These devicesarelow cost, high speed, JFET input opera-
tional amplifiers with verylow input offset voltageand guar-
anteed input offset voltage drift. They requirelow supply
currentyet maintaina large gain bandwidth productandfast
slew rate.In addition, well matched high voltage JFET input
devices provide verylow input biasand offset currents.The
LF411ispin compatible withthe standard LM741 allowing
designersto immediately upgradethe overall performance existing designs.
These amplifiers maybe usedin applications suchas high
speed integrators, fast D/A converters, sample and hold
circuits and many other circuits requiringlow input offset
voltageand drift,low input bias current, high input imped-
ance, high slewrateand wide bandwidth.
Features Internally trimmed offset voltage 0.5 mV(max) Input offset voltage drift 10 mV/§C(max) Low input bias current 50pA Low input noise current 0.01 pA/0Hz Wide gain bandwidth 3 MHz(min) High slew rate 10V/ms(min) Low supply current 1.8mA High input impedance 1012X Low total harmonic distortion AVe10, k0.02%
