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