PA52 • PA52A RoHS Power Operational Amplifiers COMPLIANT FEATURES • High Internal Dissipation — 400W • High Current — 40A Continuous, 80A Peak • High Slew Rate — 50V/µs • Optional Boost Voltage Inputs APPLICATIONS • Semi-conductor Testing • Brushless DC Motor Drive • Voltage Controlled Current Source • Electromagnetic Driver 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”. © Apex Microtechnology Inc.

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 cur- rent limit can thereby be implemented if needed. BOOST OPERATION With the V feature the small signal stages of the amplifier are operated at higher supply voltages BOOST than the amplifier’s high current output stage. +V (pin 11) and –V (pin 12) are connected to the BOOST BOOST small signal circuitry of the amplifier. +V (pin 9,10) and –V (pin 3,4) are connected to the high current out- S S put stage. An additional 10V on the V pins is sufficient to allow the small signal stages to drive the out- BOOST PA52U Rev J 9

PA52 • PA52A put 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 +V and +V pins must be strapped BOOST S together as well as the –V and –V pins. The boost voltage pins must not be at a voltage lower than the BOOST S V pins. S COMPENSATION Compensation is internally fixed for a gain of 3 or more and is not adjustable by the user. The PA52 there- fore 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 0.1µF ceramic capacitors directly at the supply pins. On the +Vs and -Vs pins use a combination of ceramic and electrolytic capacitors. Use 1µF ceramic capacitors and an electrolytic capacitor at least 10µF for each amp of output current required. NEED TECHNICAL HELP? CONTACT APEX SUPPORT!
