Analog Devices Introduces Low-Distortion High-Speed Op Amp With Unprecedented Low Noise

Motorola Semiconductor

World's leading amplifier supplier ushers in new era of signal conditioning technology.

September 29, 2003 -  Analog Devices Inc. ushered in a new era for high-speed operational amplifiers with the introduction of a new IC that minimizes two fundamental error sources in amplifier design: voltage noise and harmonic distortion. The AD8099 features a patent-pending advanced circuit architecture that addresses fundamental performance trade-offs inherent in traditional differential input stages. This enables the AD8099 to deliver both extremely low voltage noise (0.95 nV/rt Hz) and very low distortion (-90 dB at 10 MHz), a breakthrough combination of specifications that no other high-speed op amp on the market can deliver. In addition, the new device provides a 1600-V/us slew rate and a 5-GHz gain bandwidth product at gain of 10. The AD8099 can slew at rates of 600 V/us, down to a gain of 2.


New Pin-out and Packaging Enhance Performance and Ease Design Challenges
The AD8099 uses an advanced pin-out to enhance performance and stability over traditional amplifier pin-outs. The AD8099 is the first operational amplifier to use this new pin-out to reduce the mutual inductance—and resulting distortion products—caused by the coupling between positive input and negative supply. Additionally, the amplifier provides two output pins to reduce feedback parasitics. This simplifies board layout and increases the stability of the amplifier. The AD8099 is available in a lead frame chip-scale package (LFCSP). This tiny package reduces lead inductance, provides better thermal characteristics, and saves board space.

Pricing and Availability
The AD8099 is sampling now and will be in full production in November 2003. The part is rated to work over an extended industrial temperature range of -40 degrees C to +125 degrees C. It is available in two packaging options: a tiny 3 mm x 3 mm LFCSP, which reduces board space requirements and improves thermal characteristics, and the traditional low profile 8-lead SOIC (small outline integrated circuit). The parts are priced at $1.98 per unit in 1,000-piece quantities.
