GENERAL DESCRIPTION

The ADA4817-1 (single) and ADA4817-2 (dual) FastFET? amplifiers are unity-gain stable, ultrahigh speed voltage feedback amplifiers with FET inputs. These amplifiers were developed with the Analog Devices, Inc., proprietary eXtra Fast Complementary Bipolar (XFCB) process, which allows the amplifiers to achieve ultralow noise (4 nV/√Hz; 2.5 fA/√Hz) as well as very high input impedances.

With 1.3 pF of input capacitance, low noise (4 nV/√Hz), low offset voltage (2 mV maximum), and 1050 MHz ?3 dB band width, the ADA4817-1/ADA4871-2 are ideal for data acquisition front ends as well as wideband transimpedance applications, such as photodiode preamps.
