APPLICABLE PARTS (SOLD SEPARATELY)

SA09 Pin-Out

INTRODUCTION

This easy-to-use kit provides a platform for the evaluation of PWM amplifier circuits using the SA09 pin-

out. With ample breadboarding areas it is flexible enough to analyze a multitude of standard or proprietary
circuit configurations. Critical connections for power supply bypassing, compensation and current limiting are
pre-wired. Components not usually readily available in engineering labs are provided. External connection to
the evaluation kit can be made via the terminals at the edge of the circuit board. These terminal pads are suit-
able for standard banana jacks or direct soldering of wires. The schematic is shown in Figure 1.   

 Figure 1: EK Schematic

Figure 1 shows the schematic of the evaluation kit's pre-wired connections Components supplied with

the kit are marked with an asterisk (*). All other connections are made via the bread-boarding areas of the
circuit board.
