• OPTIONAL BOOST VOLTAGE INPUTS
APPLICATIONS
• SEMI-CONDUCTOR TESTING
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.
EQUIVALENT SCHEMATIC
12-pin DIP
PACKAGE STYLE CR
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”.
