DUAL HIGH POWER OPERATIONAL AMPLIFIER
8-Pin TO-3 And 12-Pin DIP, Dual 5 Amp
Operational Amplifier
FEATURES
• Available In Isolated Standard TO-3, “Copper Slug” TO-3 And
Power DIP Packages
• 5 Amp Peak Output Current
• Power Supplies to ±40V
• FET Input
• Dual Configuration
• Available Screened to MIL-STD-883
DESCRIPTION
The OMA2541 is a high performance dual power operational amplifier capable of
operation from power supplies up to ±40V and continuous output current up to 5A.
This device is ideally suited for Military motor driver, servo amplifiers, bridge amplifier,
synchro/resolver exertation as well as other power management driver applications.
Internal circuitry limits output current to approximately 6 Amps. All products are
available with Hi-Rel screening.
