The JEDEC MO-127 12-pin Power Dip鈩?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.

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 resis-
tive to the PA05. Control logic turns off the ampli鏗乪r's output
during shutdown.

DESCRIPTION
The PA05 is a high voltage MOSFET power operational
ampli鏗乪r that extends the performance limits of power ampli-
鏗乪rs in slew rate and power bandwidth, while maintaining high
current and power dissipation ratings.
The PA05 is a highly 鏗俥xible ampli鏗乪r. 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 ampli鏗乪r to
operate at a higher voltage than the high current output stage.
The ampli鏗乪r is then biased to achieve close linear swings to
the supply rails at high currents for extra ef鏗乧ient 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擄C.
