DESCRIPTION
The OPA2544 is a dual high-voltage/high-current op-
erational 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.
