Burr-Brown Announces High-Voltage, High-Current Operational Amplifier.TUCSON, Ariz.--(BUSINESS WIRE)--Nov. 10, 1999-- Burr-Brown Corporation The Burr-Brown Corporation was a United States technology company which designed, manufactured, and marketed a broad line of proprietary, standard, high-performance, analog and mixed-signal integrated circuits (ICs) used in electronic signal processing. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :BBRC BBRC Biochemical and Biophysical Research Communications BBRC Bellevue Breakfast Rotary Club (Washington state) BBRC Ball Brothers Research Corporation ) today announced the OPA OPA: see Office of Price Administration. 549, a high-voltage, high-current operational amplifier operational amplifier, amplifier whose output voltage is proportional to the negative of its input voltage and that boosts the amplitude of an input signal many times, i.e., has a very high gain. designed for power applications in industrial control, test equipment, audio, and power supplies. The OPA549's excellent combination of features, performance and price--without sacrificing dc performance--makes it ideal for driving high-current loads in industrial control (motors, valves, actuators, and solenoids), test equipment (pin drivers), power supply (voltage/current and ground drivers), and audio (powered speaker, public address, background music) applications. This single-chip power op amp eliminates the need for discrete components that consume more space and reduce reliability. Multi-chip alternatives that could be used to achieve a similar level of functionality and performance are far more expensive. "The OPA549 offers many significant advantages over customers attempting to build their own power op amp: a compact power package, reduced board area, simplified assembly, improved reliability, and lower cost," said Howard Skolnik, strategic marketing engineer at Burr-Brown. "The OPA549 extends our power op amp family by providing a 10A output current option alongside our established 750mA and 5A products." The OPA549 is internally protected against over-temperature conditions and current overloads. In addition, it provides an accurate, user-selected current limit. Unlike other designs which use a "power" resistor in series with the output current path, the OPA549 senses the load directly. This allows the current limit to be adjusted from 0A to 10A using a single, low power resistor, potentiometer, or DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter . The OPA549 provides excellent low-level signal accuracy and delivers up to 10A output current. Other features include a wide supply range (8V to 60V, single or dual supply), high slew rate (1) How fast paper moves through a printer (ips). (2) The speed of changing voltage. (9V/micro-second), wide output voltage swing, unity-gain stability, thermal overload protection, and an enable/disable function. Operation is specified over the extended industrial temperature range (-40C to +85C). The OPA549 is priced from $10.83 in 1,000 piece quantities and is available in an 11-lead power ZIP package. Delivery is from stock.
