Application Hints
The LF351 is an op amp with an internally trimmed input
offset voltage and JFET input devices (BI-FET II
TM
). These
JFETs have large reverse breakdown voltages from gate to
source and drain eliminating the need for clamps across the
inputs. Therefore, large differential input voltages can easily
be accommodated without a large increase in input current.
The maximum differential input voltage is independent of
the supply voltages. However, neither of the input voltages
should be allowed to exceed the negative supply as this will
cause large currents to flow which can result in a destroyed
unit.
Exceeding the negative common-mode limit on either input
will force the output to a high state, potentially causing a
reversal of phase to the output.
Exceeding the negative common-mode limit on both inputs
will force the amplifier output to a high state. In neither case
does a latch occur since raising the input back within the
