•
•
The LF351 is JFET input operational amplifier with an internally compensated input offset voltage. The JFET input
device provides wide bandwidth, low input bias currents and
offset currents.
Internally trimmed offset voltage: 10mV
Low input bias current : 50pA
Wide gain bandwidth : 4MHz
High slew rate : 13V/µs
High input impedance : 1012Ω
