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.
