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.
