INTRODUCTION

PWM amplifiers using the SA03 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 board is designed for surface

mounting all components except the switching amplifier.

components shown on the schematic will probably not be used

for any single circuit. Some components will simply be omit-

ted, while others require installation of a jumper to complete

the signal path.

kit. Hardware similar to that shown in figure 1 must be ob-

tained locally.

BEFORE YOU GET STARTED

* All Apex Precision Power 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.
