| FEATURES * * * * HIGH INTERNAL DISSIPATION -- 400 Watts HIGH CURRENT -- 40A Continuous, 80A PEAK HIGH SLEW RATE -- 50V/s 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 efficient operation. 12-PIN DIP PACKAGE STYLE CR 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 and/or improper mounting torque will void the product warranty. Please see "General Operating Considerations".

Unless otherwise noted: TC = 25C, DC input specifications are value given. Power supply voltage is typical rating. VBOOST = VS. 2. 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. 3. Rating applies if the output current alternates between both output transistors at a rate faster than 60 Hz. CAUTION The PA52 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 850C to avoid generating toxic fumes.

Visit www.apexmicrotech.com for design tools that help automate tasks such as calculations for stability, internal power dissipation, current limit; heat sink selection; Apex's complete Application Notes library; Technical Seminar Workbook; and Evaluation Kits. OPERATING CONSIDERATIONS COMPENSATION Compensation is internally fixed for a gain of 3 or more and is not adjustable by the user. The PA52 therefore is not unity gain stable. POWER SUPPLY BYPASSING Proper and sufficient power supply bypassing is crucial to proper operation of the PA52. Bypass the +Vb and -Vb supply pins with a minimum .1F ceramic capacitors directly at the supply pins. On the +Vs and -Vs pins use a combination of ceramic and electrolytic capacitors. Use 1F ceramic capacitors and an electrolytic capacitor at least 10F for each amp of output current required. CURRENT LIMIT There is no internal circuit provision for current limit in the PA52. However, the PA52 circuit board in the PA52 evaluation kit does provide a means whereby the output current can be sensed. An external circuit current limit can thereby be implemented if needed. See EK27 data sheet for more details. BOOST OPERATION With the VBOOST feature the small signal stages of the amplifier are operated at higher supply voltages than the amplifier's high current output stage. +VBOOST (pin 11) and -VBOOST (pin 12) are connected to the small signal circuitry of the amplifier. +VS (pin 9,10) and -VS (pin 3,4) are connected to the high current output stage. An additional 10V on the VBOOST pins is sufficient to allow the small signal stages to drive the output transistors into saturation and improve the output voltage swing for extra efficient operation when required. When close swings to the supply rails is not required the +VBOOST and +VS pins must be strapped together as well as the -VBOOST and -VS pins. The boost voltage pins must not be at a voltage lower than the VS pins.
