saFe operating area

Op Amp. For a given application,
the direction and magnitude of
the output current should be cal-
culated or measured and checked
against the SOA curves. This is
simple for resistive loads but more
complex for reactive and EMF
generating loads. The following
guidelines may save extensive
analytical efforts:
1. Under transient conditions,
* If the inductive load is driven near steady state conditions, allowing the output
2. The amplifier can handle any EMF generating or reactive load and short circuits
These simplified limits may be exceeded with further analysis using the operating
conditions for a specific application.
