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.

NOTES: 1. Differential voltages are at the noninverting input terminal with respect to the inverting
input terminal.
2. The magnitude of the input voltage must never exceed the magnitude of the supply
or 15 V, whichever is less.
3. Power dissipation must be considered to ensure maximum junction temperature (T )
J
is not exceeded (see Figure 1).
