Overview

The ADA4817-1ACP-EBZ (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 a wide supply voltage range from 5 V to 10 V and 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 analog-to-digital converter (ADC) driving. The ADA4817-1ACP-EBZ is available in a 3 mm × 3 mm, 8-lead LFCSP and 8-lead SOIC, and the ADA4817-2 is available in a 4 mm × 4 mm, 16-lead LFCSP. These packages feature a low distortion pinout that improves second harmonic distortion and simplifies circuit board layout. They also feature an exposed pad that provides a low thermal resistance path to the printed circuit board (PCB). The EPAD enables more efficient heat transfer and increases reliability. These products are rated to work over the extended industrial temperature range (−40°C to +105°C).
