RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Analog Devices Press Release - September 28, 2011

Analog Devices Announces Industry's Fastest, 1nV/√Hz,
Low Power, Rail-to-Rail Amplifiers

Visit Analog Devices

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, the ADA4896-2 (dual), ADA4897-1 (single) and ADA4897-2 (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. Watch this video and learn more about ADI's new series of high-speed amplifiers.

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 pre-amplifier.
  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.

Amplifiers Key Features
  • Low wideband noise: 1 nV/√Hz
  • Low 1/f noise: 2.4 nV/√Hz @ 10 Hz
  • Low distortion: −115 dBc @ 100 kHz, Vo= 2 V p-p
  • Low power: <3 mA
  • High speed
    • ADA4896-2, ADA4897-1, ADA4897-2
      • 30 MHz small signal bandwidth
      • 35 MHz large signal bandwidth
      • 120 V/μs slew rate
    • ADA4895-2 (de-compensated)
      • 1.5-GHz gain-bandwidth product (gain ≥+10)
      • 500-V/μs slew rate
