The complementary devices that work well with the ADA4817 include Analog Devices’ ADA493x ADC drivers and AD813x differential amplifiers.
The ADA4817-1 (single) and ADA4817-2 (dual) FastFET amplifiers are unity-gain stable, ultra-high-speed voltage feedback amplifiers with FET inputs. These amplifiers were developed with 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/vHz; 2.5 fA/vHz) 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 suitable 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.
