Power MOSFETs are transistors that can efficiently control and switch large currents. They operate at MOSFET LEVEL=3, which provides higher power handling capabilities than lower levels. Additional notation is used to indicate an even higher power rating for certain Power MOSFETs operating at MOSFET LEVEL=3+.
The THS3096 is a current-feedback amplifier, not a conventional op-amp. It has different input stage topology and gain characteristics than conventional op-amps. The open-loop gain of the current-feedback amp can be changed by adjusting the RG resistance, which shifts the gain-frequency characteristics differently than in conventional op-amps.
