PRODUCTION DATA.
The OPA172 can be used capacitive loads such as cable shields, reference buffers, MOSFET gates, and diodes. The circuit uses an isolation resistor (RISO) to stabilize the output of an op amp. RISO modifies the open-loop gain of the system to ensure the circuit has sufficient phase margin.
