INTRODUCTION
PWM amplifiers using the SA16 pin-out configuration. It can be used
to analyze a multitude of standard or proprietary circuit configura-
tions, and is flexible enough to do most standard amplifier test
configurations. The board is designed for surface mounting all
components except the switching amplifier.
nents 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.
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.
