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.cirrus.com for design tools
that help automate tasks such as calculations for stability, internal power dissipation, current limit; heat sink selec-
tion; Apex Precision Power’s complete Application Notes library; Technical Seminar Workbook; and Evaluation Kits.
CURRENT LIMIT
For proper operation, the current limit resistor (R
be connected as shown in the external connection dia-
gram. For optimum reliability the resistor value should be
set as high as possible. The value is calculated as fol-
lows; with the maximum practical value of 16 ohms.
SAFE OPERATING AREA (SOA)
The MOSFET output stage of this power operational am-
plifier has two distinct limitations:
1. The current handling capability of the MOSFET geom-
2. The junction 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.
