Burr-Brown Announces Integrated Circuit for High Performance Analog Signal Processing.TUCSON, Ariz.--(BUSINESS WIRE)--March 19, 1998--Burr burr (bur) bur. burr (bûr) n. -Brown Corporation (NASDAQ:BBRC BBRC - Ball Brothers Research Corporation Variant of bur. BBRC - Bellevue Breakfast Rotary Club (Washington state)) today announced the low noise, low distortion OPA686, a high speed 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. It is usually connected so that part of the output is fed back to the input. Operational amplifiers were originally developed to be used in synthesizing mathematical operations in analog computers, hence their name. integrated circuit offering the highest dynamic range More Realism When the music CD first came out in the mid 1980s, its dynamic range was widely touted. The CD could more accurately record the range of volume of a large orchestra from the quietest passages to the loudest drums than a vinyl phonograph record. in the industry. High dynamic range is critical to separating out individual signals in crowded digital receiver applications such as cellular basestations and cable modems. This industry-first combination of low noise and low distortion at low power make the OPA686 ideal for providing a high quality amplified signal to an analog-to-digital converter (ADC). High dynamic range performance is demanded in a wide variety of emerging applications including: IF strip amplifiers for cellular basestations where signals can interfere with one another; ultrasound imaging where low noise and low distortion are required to pull out faint echo signals; and cable modem receivers where the line reach is dependent upon the amplifier's input. In cable modem receivers, the reach (length of cable) of the signal is often limited by the level of the front-end noise. The OPA686's low noise allows the reach to be extended without compromising signal quality. Longer reach provides greater signal distribution over large areas such as high-rise apartment complexes and office buildings. According to In-Stat, a market research and information company from Scottsdale, Ariz., the cable modem market will swell from 171,000 units in 1997 to more than 10 million by 2001, resulting in a jump from revenues of $79 million in 1997 to $2.1 billion in 2001. "Using the OPA686, the entire signal processing operation is improved significantly, giving the end-user a more ideal signal to work with," said Michael Steffes, strategic marketing engineer at Burr-Brown. "In addition, the combination of low noise, distortion, power, and price gives Burr-Brown an industry leading ultra-high dynamic range op amp product family well positioned for emerging high speed data transmission in the xDSL market." OPA686 features 250MHz bandwidth at a gain of 10, 1.3nV/sqrt SQRT - Square Root(Hz) input voltage noise, -95dBc distortion at 5MHz, 600V/micro-seconds slew rate, stable for gains >=7, high DC accuracy, and +120mA/-90mA output current. OPA686 is priced from $2.89 in 1000s and packaged in tiny SOT23-5 and 8-pin SO-8 packages. Delivery for the SO-8 is from stock. The SOT23-5 will be available in April, 1998.
