Burr-Brown Announces High-Voltage, High-Current Operational Amplifiers.TUCSON, Ariz.--(BUSINESS WIRE)--Aug. 5, 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 low cost OPA OPA: see Office of Price Administration. 551 and OPA552, a pair of high-voltage, high-current operational amplifiers designed for power applications in telecommunications, audio, test and instrumentation, industrial control, and power supplies. These single-chip power op amps eliminate 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 only competition comes from customers building their own power op amp. However, the OPA551 and OPA552 surpass these attempts by providing an integrated solution with small packages, simplified assembly, higher reliability, improved performance, and increased functionality," said Howard Skolnik, strategic marketing engineer at Burr-Brown. The OPA551 and OPA552 operate on supplies up to 60V and deliver up to 200mA of drive current. Both are internally protected against over-temperature conditions and current overloads. An innovative thermal shutdown indicator alerts the user when thermal shutdown has occurred. This "flag" is easily interfaced to external logic. The OPA551 is unity gain stable and features 3MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. wide bandwidth and 15V/micro-second slew rate (1) How fast paper moves through a printer (ips). (2) The speed of changing voltage. . The OPA552 is optimized for closed-loop gain of 5 or greater and offers 12MHz bandwidth and 24V/micro-second slew rate. These laser-trimmed integrated circuits provide excellent low-level accuracy along with high output swing. High performance is maintained as the amplifier swings to its specified limits. The OPA551 and OPA552 are priced from $1.64 in 1,000 piece quantities. Both products are available in SO-8 and 8-pin PDIP (Plastic DIP) See DIP. packages, as well as the 7-lead DDPAK surface-mount package. Delivery is from stock.
