CMOS op amps come
with 'industry's fastest' tag
Texas Instruments is claiming the industry's fastest CMOS operational amplifiers, featuring 200MHz gain-bandwidth and 360V/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 ADC input buffering. 'The OPA355 is the only truly high-speed CMOS op amp on the market', said Carsten Oppitz, market development engineer for mobile communication at TI in Europe.

Webcast to address wireless power optimisation
Texas Instruments and Avnet Electronics Marketing will present a live Analog eLab webcast on 'Optimising power in low-power wireless systems' on 12th April 2006
'The OPA355 combines low-voltage operation, rail-to-rail output, digital shutdown, and low cost to deliver an unequalled solution for wide-bandwidth applications requiring exceptional AC performance'.
These voltage-feedback devices are unity-gain stable and can drive an output current of +/-100mA.
Bandwidth in unity gain is 450MHz.
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 optimised for operation on single or dual supplies, as low as 2.5V (+/-1.25V) and up to 5.5V (+/-2.75V).
Common-mode input range extends 100mV below ground and up to 1.5V from positive supply.
Output swing is within 100mV of the rails.
Other features include low noise (5.8nV/rt-Hz), low input bias current (3pA), and low quiescent current (8.3mA per channel).
The OPA355 (single) is available in SOT23-6 and SO-8 packages, and suggested resale pricing starts at $1.19 in 1000 piece quantities.
The OPA3355 (triple) is packaged in a TSSOP-14 and SO-14, and suggested resale pricing starts at $2.79 in 1000 piece quantities.
The dual OPA2355 is scheduled to be available in 3Q01.
