INTRODUCTION
Fast, easy breadboarding of circuits using the PA60EU are
possible with the PB80 PC board. Mounting holes are provided
and the provision for standard banana jacks simplifies connec-
tion and testing. The amplifier may be mounted horizontally or
vertically. Components are labeled on both sides of the board
for ease in probing.
A multitude of circuit configurations are possible, so only
several component locations have specific functions and will
usually be necessary:
C5,C8
Power supply bypasses
MUST
be used. Usually
ceramic types of 0.01 to 1.0μF.
C2, C9
Power supply bypass. Suggest 10μF per ampere of
output current.
R1
Feedback resistor.
R3
Input resistor.
R8, C10
Snubber network.
R4, C7
Noise gain compensation. Necessary only occasion-
ally, see Application Notes 19 and 25.
EQUIVALENT SCHEMATIC
The following locations should be jumpered unless used (their
most common anticipated function is listed).
R2, R10
Input protection.
CR1
V
.
R5, R6, R9
Output current sense.
The function of any other components is up to the designer’s
needs and imagination.
