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.

The specification of PA04A is identical to the specification for PA04 in applicable column to the left.
Unless otherwise noted: TC = 25°C, CC = 470pF, RC = 120 ohms. DC input specifications are ± value given. Power supply
voltage is typical rating. ±VBOOST = ±VS.
Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation
to achieve high MTTF. For guidance, refer to the heatsink data sheet.
Rating applies if the output current alternates between both output transistors at a rate faster than 60 Hz.
The PA04 must be used with a heatsink or the quiescent power may drive the unit to junction temperatures higher than 150°C.
CAUTION
The PA04 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.
