Industry's Fastest CMOS Op Amps from TI Target Video Processing and High-Performance Wide-Bandwidth Applications
TUCSON, Ariz. (Aug. 3, 2001) -- 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 amplifier, communications, and analog-to-digital converter input buffering. See http://www.ti.com/sc/aap6649u.
"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)
Available Today in MicroSize Packages
The OPA355 (single) is available in SOT23-6 and SO-8 packages, and suggested resale pricing starts at $1.19 in 1,000 piece quantities. The OPA3355 (triple) is packaged in a TSSOP-14 and SO-14, and suggested resale pricing starts at $2.79 in 1,000 piece quantities.
The dual OPA2355 is scheduled to be available in 3Q01.
