Analog Devices Announces Industry’s Fastest, 1nV/√Hz, Low Power, Rail-to-Rail Amplifiers
September 28, 2011 -- NORWOOD, Mass.--(BUSINESS WIRE)--
Analog Devices, Inc. (ADI) today unveiled a series of
high-speed amplifiers that establish a new performance standard with the best combination of high-speed, low
noise and low power. Designed for portable, multi-channel and low power instrumentation and healthcare equipment,
ADA4897-1 (single) and
(dual) high-speed amplifiers provide the highest large-signal bandwidth and slew rate with the lowest noise
available today in a
rail-to-rail amplifier under 10 mW. Each amplifier features low noise of 1 nV/√Hz and 120-V/μs slew rate while
consuming only 3 mA of supply current. Further, the 1/f noise @10Hz is a low 2.4 nV/√Hz.

Also announced as part of this high-speed amplifier series was the
ADA4895-2 dual de-compensated high-speed amplifier.
It delivers 1.5-GHz gain-bandwidth product at gains of +10 and greater, making it ideal as a high-speed, high-gain
The new rail-to-rail amplifiers operate across the extended industrial temperature range of -40˚C to +125˚C and
offer a 3-V to 10-V supply range. The ADA4895-2 and ADA4897-1/ -2 include an output disable feature.
