INTRODUCTION

linear power amplifiers circuits using the PA94/PA95 pin-out. With

ample breadboarding areas it is flexible enough to analyze a

multitude of standard or proprietary circuit configurations. Criti-

cal 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 suitable for stan-

dard banana jacks or direct soldering of wires. The schematic

is shown in Figure 1.

Add banana jacks as necessary to complete connections

to external circuits and power supplies.

Insert the amplifier into the PCB mounting holes located

in the space between the heatsink fins. So not solder the

pins at this time.

Hang the TW13 thermal washer near the end of a 6-32 X

3/8" screw. Slightly pull the amplifier away from the heat

sink face. Use the screw to position the thermal washer

behind the amplifier and insert the screw into the mounting

hole of the heatsink. Use a 6-32 nut to secure the screw

from the opposite side of the heatsink. It is important that

the entire back surface of the amplifiers mounting tab be

in contact with the heatsink. Adjust the amplifiers position

and tighten the mounting screw as necessary for this to

be so.

Solder the amplifiers pins to the PCB.

Add other passive components as necessary to complete

your circuit.

Most common configurations will ground the non-invert-

ing pin of the amplifier. J1 is a convenient way to do this

if necessary for your application circuit.

mounting #6 standoff spacers if desired.

R1-R5 are multiple feedback resistors in series. Commonly

available resistors do not have a breakdown voltage suf-

ficient to stand off the output voltage of the amplifier. Using

multiple resistors will divide down the voltage that each

resistor must withstand.
