PA162
Product Innova tionFrom
Where the PA162DK is used in higher power applications, it is necessary to use surface mount techniques of
heatsinking. Surface mount techniques include the use of a surface mount fan in combination with a surface mount
heatsink on the backside of the FR4/ PC board with through hole thermal vias. Other highly thermal conductive
substrate board materials are available for maximum heat sinking.
The Power Derating graph assumes that the power dis-
sipation is equal in each of the amplifiers. Power and ther-
mal ratings are based on two separate dual monolithic
power op amps on one integrated copper heat slug. Amps
A and B are combined on one monolithic die while amps
C and D are combined on the other. This multi chip con-
figuration provides superior thermal performance by iso-
lating each of the dual amplifiers. When loading either of
the dual amplifiers it is possible to achieve better thermal
performance by loading any combination of amplifiers (A
or B) + (C or D).
MOUNTING PRECAUTIONS
1. Always use a heat sink. Even unloaded the PA162DK
can dissipate up to .8 watts.
2. Avoid bending the leads. Such action can lead to inter-
nal damage.
