GENERAL
Please read Application Note 1 "General Operating Considerations" which covers stability, supplies, heat sinking,
mounting, current limit, SOA interpretation, and specification interpretation. Visit www.apexmicrotech.com for de-
sign tools that help automate tasks such as calculations for stability, internal power dissipation, current limit; heat
sink selection; Apex’s complete Application Notes library; Technical Seminar Workbook; and Evaluation Kits.
SAFE OPERATING AREA (SOA)
40"
The output stage of most power amplifiers has three distinct
limitations:
1. The current handling capability of the transistor geometry
and the wire bonds.
2. The second breakdown effect which occurs whenever the
simultaneous collector current and collector-emitter volt-

age exceeds specified limits.
3. The junction temperature of the output transistors.
The SOA curves combine the effect of all limits for this Power
Op Amp. For a given application, the direction and magnitude
of the output current should be calculated or measured and
checked against the SOA curves. This is simple for resistive

loads but more complex for reactive and EMF generating
loads. However, the following guidelines may save extensive analytical efforts.
