•
•
•
The LF353 is a 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
