INTRODUCTION

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

PWM amplifiers using the SA08 pin-out configuration. It can be

used to analyze a multitude of standard or proprietary circuit

configurations, and is flexible enough to do most standard

amplifier test configurations.

The schematic is shown in Figure 3. Note that all of the

components shown on the schematic will probably not be used

for any single circuit. Some components will simply be omitted,

while others require installation of a jumper to complete the

signal path.

Only components unique to the EK15 are provided in this kit.

Hardware similar to that shown in Figure 1 must be obtained

locally.

BEFORE YOU GET STARTED

* All Apex amplifiers should be handled using proper ESD

precautions.

* Always use the heatsink included in this kit with TW05

washer.

* 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.
