DESCRIPTION
The OPA2544 is a dual high-voltage/high-current operational amplifier suitable for driving a wide variety
of high power loads. It provides 2A output current and
power supply voltage range extends to ±35V.
The OPA2544 integrates two high performance FET
op amps with high power output stages on a single
monolithic chip. Internal current limit and thermal
shutdown protect the amplifier and load from damage.
The OPA2544 is available in a 11-lead plastic
packages and is specified for the –40°C to +85°C
temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
