MICROCIRCUIT DATA SHEET MJLF412-X
OFFSET, DRIFT DUAL JFET INPUT OPERATIONAL AMPLIFIER
These devices cost, high speed, JFET input operational amplifiers with very input offset voltage guaranteed input offset voltage drift. They require supply current maintain large gain bandwidth product fast slew rate. addition, well matched high voltage JFET input devices provide very input bias offset currents. LF412 dual compatible with LM1558, allowing designers immediately upgrade overall performance existing designs. These amplifiers used applications such high speed integrators, fast converters, sample hold circuits many other circuits requiring input offset voltage drift, input bias current, high input impedance, high slew rate wide bandwidth.
