PIN DESCRIPTIONS
3. GENERAL
Please read Application Note 1 “General Operating Considerations” which covers stability, power 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
selection, complete Application Notes library, Technical Seminar Workbook and Evaluation Kits.
CAUTION
In order to achieve the highest speed with limited space short circuit protection and thermal protection were sacri-
ficed. Do not short the output. Note that if current limiting at 1.5 A could be used, and the output was shorted, internal
dissipation would be 150 W. This would still destroy the amplifier, albeit more slowly.
4. INTERNAL POWER DISSIPATION AND HEATSINK SELECTION
With the unique combination of high voltage and speed of the PA107, traditional formulas for heatsink selection
will falsely lower the apparent power handling capability of this amplifier. To predict operating temperatures use the
following procedure:
Find internal dissipation (PD) resulting from driving the load. Refer to Apex Applications Note 1, General Operating
Considerations, paragraph 7. Find total quiescent power (PD
plus 0.021 times the total V
V
Calculate a heatsink rating which will maintain the case at 85°C or lower.
Where:
Calculate a heatsink rating which will maintain output transistor junctions at 150°C or lower.
Where:
Use the larger heatsink of these two calculations.
