DESCRIPTION
The PA33 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 PA33 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 perfor-
mance 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.

TYPICAL APPLICATION
The high power bandwidth of the PA33 allows driving sonar
transducers via a resonant circuit including the transducer and
a matching transformer. The load circuit appears resistive to
the PA33. Control logic turns off the amplifier's output during
shutdown.

The DIP04 12-pin package (see Package Outlines) is
hermetically sealed and isolated from the internal circuits. The
use of compressible thermal washers and/or improper mount-
ing torque will void the product warranty. Please see “General
Operating Considerations”.
