These JFET input operational amplifiers are designed for low power

LOW POWER

applications. They feature high input impedance, low input bias current and low input offset current. Advanced design techniques allow for higher slew JFET INPUT rates, gain bandwidth products and output swing. The LF441C device

OPERATIONAL AMPLIFIERS

provides for the external null adjustment of input offset voltage. These devices are specified over the commercial temperature range. All

SEMICONDUCTOR

are available in plastic dual in–line and SOIC packages.
