ADA4817-2:  Low Noise, 1 GHz FastFET Op Amps

Product 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 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.

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).
