These JFET input operational amplifiers are designed for low power  
applications. They feature high input impedance, low input bias current and  
low input offset current. Advanced design techniques allow for higher slew  
rates, gain bandwidth products and output swing. The LF441C device  
provides for the external null adjustment of input offset voltage.
