OPA2544BM

The OPA2544BM is one member of the OPA2544 series.It has the following features including (1)HIGH OUTPUT CURRENT: 2A min;(2)INTERNAL CURRENT LIMIT;(3)High Surge Capability;(4)THERMAL SHUTDOWN PROTECTION;(5)11-LEAD PLASTIC PACKAGE.

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.The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions.

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.The OPA2544 has an internal current limit set for approximately 4A. This current limit decreases with increasing junction temperature as shown in the typical curve, Current Limit versus Temperature. This, in combination with the thermal shutdown circuit, provides protection from many types of overload. It may not, however, protect for shortcircuit to ground, depending on the power supply voltage, ambient temperature, heat sink and signal conditions.
