OMA541SK OMA541SKC OMA541SD OMA541SDZ HIGH POWER, HIGH CURRENT OPERATIONAL AMPLIFIER 8-Pin, TO-3 And DIP, 10 Amp Monolithic Power Operational Amplifier FEATURES * Available In Isolated Standard TO-3, "Copper Slug" TO-3 And Power DIP Packages * 10 Amp Peak Output Current * Power Supplies to 40V * Programmable Current Limit * FET Input * Available Screened to MIL-STD-883 DESCRIPTION The OMA541 is a power operational amplifier capable of operation from power supplies up to 40V and continuous output current up to 5A. Internal current limit circuitry can be user-programmed with a single external resistor, protecting the amplifier and load from fault conditions. The OMA541 pinout is compatible with popular power operational amplifiers such as the OPA511, OPA512 and OPA3573. This device is ideally suited for Military motor driver, servo amplifier, synchro exertation as well as other power drive circuitry. The OMA541SKC incorporates a copper slug to the header for improved thermal performance.
