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 and approved to DESC drawing 5962-90838.

NOTES:
(1) Unless otherwise specified, these tests are for each amplifier.
(2) Internal current limit circuitry is controlled by a single external resistor, R
CL
. To calculate the value of the current limit
resistor, use R
CL
= (0.809/I
LIM
) - 0.057, where I
LIM
is equal to the desired output current (I
OP
).
(3) Assumes equal dissipation in both amplifiers.
• Denotes over specified temperature range.
