Burr-Brown Unveils Industry's Fastest Current-Feedback Op Amp.TUCSON, Ariz.--(BUSINESS WIRE)--April 30, 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. 685, a high-speed, current-feedback operational amplifier The current feedback operational amplifier or CFB op-amp is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback (VFB) operational amplifier. optimized for medium to high gain operation and intended for wireless communications, cable modems, and high resolution video graphics applications. The low cost OPA685 combines ultra-high bandwidth with exceptional slew rate and low noise as required of IF amplifiers in wireless receivers. At medium gains (G = 8 with BW > 400MHz (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. ), it provides high linearity and load isolation in this critical communications application. For cable modem consumer applications, it can provide the high power with low distortion required through 65MHz. At lower gains (G = 2 with BW >900MHz), the OPA685 provides the highest speed video line driver for high-resolution workstation graphics pixel rates. This gives sharper pixel resolution pixel resolution Telemedicine The sharpness of a computerized image, based on pixel concentration, which determines display resolution at the monitor. "The OPA685 establishes a new level of performance for high speed op amps," said Michael Steffes, strategic marketing engineer at Burr-Brown. "Previous high speed op amps drop to under 200MHz when operated at higher gains where the OPA685 holds over 400MHz to gains of 10. The low power and cost at this performance level provide significant advantages to wireless and cable modem designs." The OPA685's low 12.6mA supply current is precisely trimmed at +25 degrees Celsius. This trim, along with low temperature drift, guarantees low system power over temperature. Using the optional disable control pin, system power may further be reduced to less than 200 micro-amps. This power-savings feature, along with exceptional single +5V operation and ultra-small SOT23-6 packaging, meets the requirements of portable communications. Additional features include high slew rate (4200V/micro-second, G = 8), low input noise voltage (1.7nV/sqrt-Hz), and high 3rd-order intercept (>40dBm). The OPA685 is priced from $1.89 in 1,000 piece quantities and packaged in an SO-8 or SOT23-6 package. Delivery is from stock.
