Low Offset, Low Drift Dual JFET Input Operational Amplifier
LF412
Low Offset, Low Drift Dual JFET Input Operational
Amplifier
General DescriptionThese devices are low cost, high speed, JFET input opera-
tional amplifiers with very low input offset voltage and guar-
anteed input offset voltage drift. They require low supply
currentyet maintaina 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
LF412 dualis pin compatible with the LM1558, allowing
designersto immediately upgradethe overall performanceof
existing designs.
These amplifiers maybe usedin applications suchas 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 imped-
ance, high slew rate and wide bandwidth.
Features Internally trimmed offset voltage: 1 mV (max) Input offset voltage drift: 10 µV/˚C (max) Low input bias current: 50pA Low input noise current: Wide gain bandwidth:3 MHz (min) High slew rate: 10V/µs (min) Low supply current: 1.8 mA/Amplifier High input impedance: 1012Ω Low total harmonic distortion ≤0.02% Low1/f noise corner: 50Hz Fast settling timeto 0.01%:2µs
