8.2 Typical Application

This circuit can drive capacitive loads (such as cable shields, reference buffers, MOSFET gates, and diodes). The circuit uses an isolation resistor (R_ISO) to stabilize the output of an operational amplifier. R_ISO modifies the open-loop gain of the system to ensure that the circuit has sufficient phase margin.
