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 are

developed in 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 a wide supply voltage range from 5 V to 10 V, 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.

The ADA4817-1 is available in a 3 mm × 3 mm 8-lead LFCSP

and the ADA4817-2 is available in a 4 mm × 4 mm 16-lead LFSCP.

Both packages feature a low distortion pinout, which improves

second harmonic distortion and simplifies the layout of the

circuit board. In addition, both packages feature an exposed

paddle that provides a low thermal resistance path to the

printed circuit board (PCB). This enables more efficient heat

transfer and increases reliability. Both products are rated to

work over the extended industrial temperature range (−40°C

to +105°C).

With 1.5 pF of input capacitance, low noise (4 nV/√Hz),

low offset voltage (2 mV maximum), and 1050 MHz −3 dB

bandwidth, the ADA4817-1/ADA4871-2 are ideal for data

acquisition front ends as well as wideband transimpedance

applications, such as photodiode preamps.
