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. These devices are specified over the commercial temperature range. All are available in plastic dual in–line and SOIC packages.

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 (TJ) is not exceeded (see Figure 1).
