ASSEMBLY

During assembly refer to Figure 1

1. Note that each circuit board side is identiﬁed. From the

circuit side of the circuit board (not the component side)

insert and solder cage jack MS04 at pins 1-12. Be sure

that the cage jack sits ﬂush with the surface of the circuit

board.

2. Solder the surface mount ceramic capacitors to the com-

ponent of the circuit board at C3-C7.

3. Mount the electrolytic capacitors at C1 and C2 from the

component side of the circuit board and solder from the

circuit side of the circuit board. Note polarity and be sure

to ﬁll the holes with solder. Use correct voltage capacitor

for your application.

4. Mount the terminal strip TS02 to the component side of the

circuit board. Make sure the terminal strip sits ﬂat against

the circuit board and be sure to ﬁll the holes with solder.

5. Use #14 sleeving to insulate and align at least 2 opposite

pins of the ampliﬁer.

6. Add other components to complete your circuit design. Note

that the solder terminals labeled 2 and 3 are left for you to

connect to the ampliﬁer via the components that you will

add for your particular design.

7. Push the four nylon spacers into the circuit board from

the circuit side of the circuit board at the four corner loca-

tions.

8. Apply TW05 thermal washer to the bottom of the PA50.

Mount the ampliﬁer to the HS18 heat sink provided and

loosely attach with #6 screw and nut.

9. Place the assembled circuit board over the pins of the

ampliﬁer making sure that the pin 1 location on the circuit

board matches up with pin 1 of the ampliﬁer. Insert the pins

of the ampliﬁer into the circuit board mating cage jacks.

10. Mount the circuit board assembly to the heat sink with #6

self tapping or sheet metal screws at the four corners of

the heat sink.

11. Tighten the screws that mount the ampliﬁer to the heat sink

via the access holes in the circuit board.

Evaluation Kit for PA50, PA52 Power Op Amps

INTRODUCTION

This easy-to-use kit provides a platform for the evaluation of

linear power ampliﬁers circuits using the PA50/PA52 pin out.

With ample breadboarding areas it is ﬂexible enough to analyze

a multitude of standard or proprietary circuit conﬁgurations.

Critical connections for power supply bypassing are pre-wired.

Components not usually readily available in engineering labs

are provided. External connection to the evaluation kit can be

made via the terminal block and terminal pads at the edges of

the circuit board. The terminal pads are suitable for soldering

standard banana jacks or direct soldering of wires.The schematic

is shown in Figure 2.

BEFORE YOU GET STARTED

* All Apex Precision Power ampliﬁers should be handled using

proper ESD precautions.

* Do not change connections while the circuit is powered.

* Initially set all power supplies to the minimum operating volt-

age allowed in the device data sheet.
