Application Hints
The LF147 is an op amp with an internally trimmed input off-
set voltage and JFET input devices (BI-FET II). 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 ac-
commodated without a large increase in input current. The
maximum differential input voltage is independent of the sup-
ply 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 re-
versal 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 common-mode range
again puts the input stage and thus the amplifier in a normal
operating mode.
