OPERATING

CONSIDERATIONS

SAFE OPERATING AREA (SOA)

The MOSFET output stage of this power operational

amplifier has two distinct limitations:

1. The current handling capability of the die metallization.

2. The temperature of the output MOSFETs.

NOTE: The output stage is protected against transient

flyback. However, for protection against sustained, high energy

flyback, external fast-recovery diodes should be used.
