EK01 Evaluation Kit APPLICABLE PARTS (SOLD SEPARATELY) SA01 INTRODUCTION This easy-to-use kit provides a platform for the evaluation of PWM amplifiers using the SA01 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 board is designed for surface mounting all components except the switching amplifier. 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 EK01 are provided in this kit. Hardware similar to that shown in Figure 7 must be obtained locally. The PC board and the foot print of the heatsink measure 3 by 5 .
