INTRODUCTION
This easy-to-use kit provides a platform for the evaluation
of PWM amplifier circuits using the SA07 pin-out. With ample
breadboarding areas it is flexible enough to analyze a multitude
of standard or proprietary circuit configurations. Critical con-
nections 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 suitable for standard
banana jacks or direct soldering of wires. The schematic is
shown in Figure 1.

ASSEMBLY
See Figure 3.
1. Solder the surface mount ceramic capacitors to the DUT side
of the circuit board at CVs and CVcc.
2. Select a current limiting resistor from the two values provided.
See the product data sheet for information on how to select a
value. Apply a thin coating of thermal grease to the back of
the resistors. Press the resistor body onto the circuit board
foil at positions Ra and Rb and solder the leads.
3. Assemble the amplifier, thermal washer and heat sink to the
circuit board as illustrated in Figure 1. As a last step push
the clip through the heat sink and circuit board until it locks.
Solder the amplifier pins to the circuit side of the circuit
board.
4. The four holes at the corners of the circuit board are for
mounting #6 standoff spacers if desired.
5. Add other components as necessary to complete your ap-
plication circuit.
BEFORE YOU GET STARTED
* All Apex amplifiers should be handled using proper ESD
precautions.
* Always use thermal grease between the amplifier and heat-
sink.
* 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.
