The availability of the compensation terminal permits the use
of feedforward frequency compensation to enhance slew
rate. The voltage follower feedforward scheme bypasses the
amplifier’s gain stages and slews at nearly 10V/
s.
The inputs of the LT1097 are protected with back-to-back
diodes. In the voltage follower configuration, when the
input is driven by a fast, large signal pulse (>1V), the input
protection diodes effectively short the output to the input
during slewing, and a current, limited only by the output
short circuit protection will flow through the diodes.
The use of a feedback resistor, as shown in the voltage
follower feedforward diagram, is recommended because
this resistor keeps the current below the short circuit limit,
resulting in faster recovery and settling of the output.
