INTRODUCTION
This easy-to-use kit provides a platform for the evaluation
of linear power ampliers circuits using the PA97 pin-out. With
ample breadboarding areas it is exible enough to analyze
a multitude of standard or proprietary circuit congurations.
Critical connections for power supply bypassing 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
1. See Figure 1. Insert and solder the TransZorb diodes at D3
and D4 (440V).
2. Insert and solder the disc bypass capacitors at C1 and C2.
3. Jumper R
LIM and RC
Note that heatsink HS28 is not used.
4. Add banana jacks as necessary to complete connections to
external circuits and power supplies.
5. Insert the amplier into the PCB mounting holes located in
the space between the heatsink ns (not used) and solder
pins.
6. Add other passive components as necessary to complete
your circuit.
7. Most common congurations will ground the non-inverting pin
of the amplier. J1 is a convenient way to do this if necessary
for your application circuit.
8. The four holes at the corners of the circuit board are for
mounting #6 standoff spacers if desired.
9. R1-R5 are multiple feedback resistors in series. Commonly
available resistors do not have a breakdown voltage sufcient
to stand off the output voltage of the amplier. Using multiple
resistors will divide down the voltage that each resistor must
withstand.
FIGURE 1.
Figure 1 shows the schematic of the evaluation kit's pre-wired
connections. Components supplied with the kit are marked with
an asterisk (*). See the amplier's data sheet for full applica-
tion information.
