AMPLIFIER APPROVEDTO DESC DRAWING 5962-87620
8-Pin TO-3 And 10-Pin DIP, 10 Amp
Operational Amplifier
FEATURES
• Approved to DESC 5962-87620
• Available In Isolated Standard TO-3, “Copper Slug” TO-3 And
Power DIP Packages
• 10 Amp Peak Output Current
• ±10V to ±40V Supply Range
DESCRIPTION
The OMA501 is a high power operational amplifier capable of 260 watts peak output
power. The high current output stage delivers ±10A, yet the amplifier is unity-gain
stable and it can be used in any operational amplifier configuration. This device is
ideally suited for Military motor driver, servo amplifiers, actuator control and other
power drive circuits. All products are available with Hi-Rel screening and approved to
DESC drawing 5962-87620.
