SA12 PWM Amplifier
INTRODUCTION
This easy-to-use kit provides a platform for the evaluation of PWM amplifiers using the SA12 pin-out con-
figuration. It can be used to analyze a multitude of standard or proprietary circuit configurations, and is flexi-
ble enough to do most standard amplifier test configurations.
The schematic is shown in Figure 2. Note that all of the components shown on the schematic will proba-
bly not be used for any single circuit. Some components will simply be omitted, while others require installa-
tion of a jumper to complete the signal path.
Only components unique to the EK17 are provided in this kit. Hardware similar to that shown in Figure 4
must be obtained locally.
