INTRODUCTION
way to breadboard design ideas for the PA78EU power opera-
tional amplifiers. The EVAL60 evaluation board is pre-wired for
all required and recommended external components including
the ones for power supply bypassing, compensation and cur-
rent limiting. The EVAL60 also includes a breadboard area for
constructing your application circuit with provisions for a pre-
amplifier to drive the PA78 inputs.

RC+) based on the closed loop gain and capacitive
load. Add the current limit resistor (RLIM) based on load
requirements (a minimum value of 4.5 ohms should be
used to protect the PA78 internal output devices). It is
recommended to use MSO2 sockets for the components
for quick component changes on the board. Add 33pF
capacitor (CT) between DUT pins 3 and 5.

for two extra banana jacks (P4 and P5) and can be used
if desired for external connections.
the DUT side of the board.
want to use the mating socket strip. Use the MS11 socket
strip for mounting the PA78 EU. Clip off the strip after the
12th position. Insert the strip into the circuit board on the
DUT side and solder one pin on the reverse side. Check
whether the mating socket strip is fully seated against the
circuit board and then solder the remaining pins. Insert
the amplifier fully into the socket strip, noting the pin 1
location on the amplifier and the circuit board.
SOA considerations) mount the heat sink (HS27) in the
outlined area on the circuit board.
the amplifier in such a way that the hole on the washer
coincides with the hole on the tab and the heat sink.
