EVALUATION KIT
There are two evaluation kits available. For applications exceeding an internal power dissipation of 10 Watts, use
the EK16. For lower power dissipation, use the EK11. The evatuation kits are easy to use engineering platforms
for prototype evaluation. They accommodates only the straight pin version of the amplifier. The PC board is also a
good starting point for an application specific layout. Provided items include: PC board, heatsink rated at 5.3°C/W
or 1.3°C/W, socket, thermal washers, ceramic bypass capacitors and transient voltage suppressors. The amplifier
is sold separately. Common hardware such as screws, nuts and user’s preference for I/O connectors are not pro-
vided.
HEATsINKs
The following heatsinks are mechanically compatible with this amplifier. Thermal ratings are for optimum mounting
in free air.
Hs20
The HS20 is designed to be fastened vertically to a PC
board with screws.
Many other heatsinks can be used with this amplifier if a hole is drilled and deburred. Requirements for the potential
heatsink or chassis member are flatness of 2 mils per inch in an area large enough to fit the package.
sOCKET
Ms06
Part number MS06 consists of 2 socket strips. These are
mounted directly in a print circuit board. Use a spacer be-
tween the PCB and the heatsink to avoid short circuits.
