DESCRIPTION

The PA52 is a 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.

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 ef-

ficient operation.

EQUIVALENTSCHEMATIC

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

and/or improper mounting torque will void the product warranty.

Please see “General Operating Considerations”.
