The LF453 is a low-cost, high-speed, dual JFET-input oper-  
ational amplifier with an internally trimmed input offset volt-  
age (BI-FET II technology). The device requires a low supply  
current and yet the amplifiers maintain a large gain band-  
width product and a fast slew rate. In addition, well matched  
high voltage JFET input devices provide very low input bias  
and offset currents. The LF453 is pin compatible with the  
standard LM1558, allowing designers to upgrade the overall  
performance of existing designs.

The LF453 may be used in such applications as high-speed  
integrators, fast D/A converters, sample-and-hold circuits  
and many other circuits requiring low input bias current, high  
input impedance, high slew rate and wide bandwidth.
