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.

DESCRIPTION
The PA04 is a high voltage MOSFET power operational amplifier that extends the performance limits of power amplifiers 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 operation 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 DipTM package (see Package Outlines) is hermetically sealed and isolated from the internal circuits. The use of compressible thermal washers will void product warranty.

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. 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.
