DESCRIPTION
The PA04 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 PA04 is a highly flexible amplifier. The sleep mode
feature allows ultra-low quiescent current for standby opera-
tion or load protection by disabling the entire amplifier. 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 performance 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 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 will
void product warranty.

TYPICAL APPLICATION
The high power bandwidth and high voltage output of the
PA04 allows driving sonar transducers via a resonant circuit
including the transducer and a matching transformer. The load
circuit appears resistive to the PA04. Control logic turns off the
amplifier in sleep mode.
