General Description
The LF453isa low-cost, high-speed, dual JFET-input oper-
ational amplifierwithan internally trimmed input offset volt-
age(BI-FETII technology).The device requiresa lowsupply
current andyetthe amplifiers maintaina large gain band-
widthproduct andafast slewrate.In addition,well matched
high voltage JFET input devices provide verylow inputbias
and offset currents. The LF453ispin compatible withthe
standard LM1558,allowing designersto upgradethe overall
performanceof existing designs.
The LF453 maybe usedin such applicationsas high-speed
integrators, fast D/A converters, sample-and-hold circuits
and manyothercircuits requiringlow input bias current,high
input impedance, high slew rateand wide bandwidth.
Features Internally trimmed offset voltage 5.0mV (max) Low input bias current 50pA (typ) Low input noise current 0.01 pA/SHz (typ) Wide gain bandwidth 4 MHz (typ) High slew rate 13 V/ms (typ) Low supply current 6.5mA (max) High input impedance 1012X (typ) Low total harmonic distortion k0.02% (typ)e10,RLe 10k,e20 Vp–p,fe20 Hz–20kHz Low1/f noise corner 50Hz (typ) Fast settling timeto 0.01% 2ms (typ)
