TUCSON, AZ -- Texas Instruments (TI) Incorporated (NYSE: TXN) today announced the industry's fastest CMOS operational amplifiers, featuring 200-MHz gain-bandwidth and 360-V/us slew rate. This new op amp family from the company's Burr-Brown product line provides the wide bandwidth and high performance critical to high-speed applications such as video processing, ultrasound, optical networking, photodiode transimpedance amplifier, communications, and analog-to-digital converter input buffering. "The OPA355 is the only truly high-speed CMOS op amp on the market," said Frank Haupt, strategic marketing engineer of TI's high-performance amplifier products. "The OPA355 combines low-voltage operation, rail-to-rail output, digital shutdown, and low cost to deliver an unequaled solution for wide-bandwidth applications requiring exceptional AC performance." These voltage-feedback devices are unity-gain stable and can drive an output current of +/-100-mA. Bandwidth in unity gain is 450-MHz. Low differential gain and phase error is ideal for demanding video processing applications. All versions (single, dual, and triple) feature a digital shutdown function which provides power savings during idle periods and places the output in a high-impedance state to support output multiplexing. The OPA355 family is optimized for operation on single or dual supplies, as low as 2.5-V (+/-1.25-V) and up to 5.5-V (+/-2.75-V). Common-mode input range extends 100-mV below ground and up to 1.5-V from positive supply. Output swing is within 100-mV of the rails. Other features include low noise (5.8-nV/rt-Hz), low input bias current (3-pA), and low quiescent current (8.3-mA per channel). For further information visit www.ti.com
