PA50 PPA50 PA50AA50A PA50, PA50A Power Operational Amplifier FEATURES HIGH INTERNAL DISSIPATION 400 Watts HIGH CURRENT 40A Continuous, 100A PEAK HIGH SLEW RATE 50V/s OPTIONAL BOOST VOLTAGE INPUTS APPLICATIONS SEMI-CONDUCTOR TESTING DESCRIPTION 12-PIN DIP The PA50 is a MOSFET power operational amplifier that PACKAGE STYLE CR extends the performance limits of power amplifiers in slew rate and power bandwidth, while maintaining high current and power dissipation ratings. The JEDEC MO-127 12-pin Power Dip package (see Boost voltage inputs allow the small signal portion of the Package Outlines) is hermetically sealed and isolated from amplifier to operate at a higher voltage than the high current the internal circuits. The use of compressible thermal wash- output stage. The amplifier is then biased to achieve close ers and/or improper mounting torque will void the product linear swings to the supply rails at high currents for extra ef- warranty.

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. The PA50 is constructed from MOSFET transistors. ESD handling procedures must be observed. CAUTION 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. 2 PA50U
