Norwood, MA (01/20/2009) - Analog Devices, Inc. (ADI), the world leader in data converters and high-speed amplifiers, introduced today one of the industry’s fastest field-effect transistor operational amplifiers currently available. Operating to 1 GHz, the ADA4817 is designed for high-performance medical diagnostic and portable devices, as well as instrumentation equipment. It provides twice the bandwidth with half the noise of competing devices. It is already designed in at top medical and test and measurement companies for applications such as CT, MRI, scope probe and other medical devices. Complementary devices that work well with the ADA4817 include Analog Devices’ ADA493x ADC drivers and AD813x differential amplifiers.

The single (ADA4817-1) and dual (ADA4817-2) FastFET amplifiers are unity-gain stable, ultra-high-speed voltage feedback amplifiers with FET inputs. These amplifiers are fabricated on ADI’s proprietary eXtra Fast Complementary Bipolar process, which allows the amplifiers to achieve the unique combination of high speed and ultra-low noise (4 nV/√Hz; 2.5 fA/√Hz) as well as very high input impedance.

With low noise, low offset voltage (2 mV maximum), 1.5 pF of input capacitance, and 1050-MHz −3 dB bandwidth, the ADA4817-1/ADA4871-2 are highly effective for data acquisition front ends as well as wideband transimpedance applications, such as photodiode preamps. A voltage range from 5 V to 10 V gives these FastFET amplifiers the ability to operate on either single or dual supplies. The ADA4817-1/ ADA4817-2 are designed to work in a variety of applications, including active filtering and ADC driving.
