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.
