DESCRIPTION
The PA05 is a high voltage MOSFET power operational
amplifier that extends the performance limits of power ampli-
fiers in slew rate and power bandwidth, while maintaining high
current and power dissipation ratings.
The PA05 is a highly flexible amplifier.The shutdown control
feature allows the output stage to be turned off for standby
operation or load protection during fault conditions. Boost
voltage inputs allow the small signal portion of the amplifier to
operate at a higher voltage than the high current output stage.
The amplifier is then biased to achieve close linear swings to
the supply rails at high currents for extra efficient operation.
External compensation tailors slew rate and bandwidth per-
formance to user needs. A four wire sense technique allows
precision current limiting without the need to consider internal
or external milliohm parasitic resistance in the output line.The
output stage is protected by thermal limiting circuits above
junction temperatures of 175°C.

12-pin Power DIP
PACKAGE STYLE CR
The JEDEC MO-127 12-pin Power Dip™ package (see
Package Outlines) is hermetically sealed and isolated from
the internal circuits.The use of compressible thermal washers
and/or improper mounting torque will void the product warranty.
Please see “General Operating Considerations”.
TYPICAL APPLICATION
The high power bandwidth of the PA05 allows driving sonar
transducers via a resonant circuit including the transducer and
a matching transformer. The load circuit appears resistive to
the PA05. Control logic turns off the amplifier's output during
shutdown.

3. Rating applies if the output current alternates between both output transistors at a rate faster than 60 Hz.
4. The PA05 must be used with a heatsink or the quiescent power may drive the unit to junction temperatures higher than 150°C.
CAUTION
The PA05 is constructed from MOSFET transistors. ESD handling procedures must be observed.
The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or
subject to temperatures in excess of 850°C to avoid generating toxic fumes.
