Low Power JFET Input
Operational Amplifiers
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.
These devices are specified over the commercial temperature range. All
are available in plastic dual in–line and SOIC packages.
