General Description
These devices are low cost, high speed, dual JFET input
operational amplifiers with an internally trimmed input offset
voltage (BI-FET II™ technology). They require low supply
current yet maintain a 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
TL082 is pin compatible with the standard LM1558 allowing
designers to immediately upgrade the overall performance of
existing LM1558 and most LM358 designs.
These amplifiers may be used in applications such as high
speed integrators, fast D/A converters, sample, and hold
circuits and many other circuits requiring low input offset
voltage, low input bias current, high input impedance, high
slew rate and wide bandwidth. The devices also exhibit low
noise and offset voltage drift.
