INTRODUCTION
The EK14 evaluation kit provides a convenient way to bread-
board circuits using Apex power op amps packaged in the 12-pin
SIP03 package. The amplifier may be mounted vertically with
the HS20 heat sink, or horizontally. Connections are provided
for required power supply bypassing, external compensation
components, as well as current limit resistors. A large area for
component mounting provides flexibility and makes a multitude
of circuit configurations possible.
CAUTION
Use the supplied thermal washers or ther-
mal grease between the power amplifier
and the heat sink.

BEFORE YOU GET STARTED
All Apex amplifiers should be handled using proper ESD
precautions.
Always use the heat sink and thermal washers included in
this kit.
Always use adequate power supply bypassing.
Do not change connections while the circuit is powered.
Initially set all power supplies to the minimum operating levels
allowed in the device data sheet.
Check for oscillations.
ASSEMBLY
1. On the silk screen side of the evaluation board, insert and
solder the MS06 mating socket in DUT holes 1 12. Be sure
each one is fully seated.
2. Solder components for your circuit. Be sure to include proper
bypassing, required compensation components and current
limit resistors. See the op amp data sheet for help in select-
ing these components. 1uF capacitors and a .15 resistor
have been included with the EK12 kit but may be replaced
with other components as necessary.
3. Place the TW07 thermal washer on the heat sink over the
mounting hole for the DUT. Place a #6 screw through the
mounting hole and thread a #6 nut onto the screw at the
back of the heat sink. Do not tighten. Note that there are
two sets of mounting holes on the HS20. Holes on one edge
allow room between the DUT and evaluation board for the
MS06 socket. The holes on the other edge are for direct
through hole mounting of the DUT to the evaluation board.
It is recommended that you use the MS06.
4. Mount the DUT to the HS20 by sliding under the head of the
#6 screw and on top of the thermal washer. Tighten the nut
to the specified 8 to 10 in-lbs. (.9 to .13 N*M). Do not over
torque.
5. Install leads of the DUT into the MS06 on the evaluation board.
Use #6 self-tapping screws to secure the evaluation board
to the HS20 heat sink as shown in the assembly diagram
(Figure 1).
