DESCRIPTION

The PA52 is a MOSFET power operational amplifier that extends the performance limits of power amplifi-

ers 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 efficient operation.

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 Application Note 1, “General Operating Considerations”.
