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 LF353-N

is pin compatible with the standard LM1558 allowing

designers to immediately upgrade the overall

performance of existing LM1558 and 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.
