GENERAL DESCRIPTION

The AD8067 FastFET amp is a voltage feedback amplifier with

FET inputs offering wide bandwidth (54 MHz @ G = +10) and

high slew rate (640 V/µs). The AD8067 is fabricated in a

proprietary, dielectrically isolated eXtra Fast Complementary

Bipolar process (XFCB) that enables high speed, low power, and

high performance FET input amplifiers.

The AD8067 is designed to work in applications that require

high speed and low input bias current, such as fast photodiode

preamplifiers. As required by photodiode applications, the laser

trimmed AD8067 has excellent dc voltage offset (1.0 mV max)

and drift (15 µV/°C max).

The FET input bias current (5 pA max) and low voltage noise

(6.6 nV/√Hz) also contribute to making it appropriate for precision

applications. With a wide supply voltage range (5 V to 24 V)

and rail-to-rail output, the AD8067 is well suited for a variety of

applications that require wide dynamic range and low distortion.

The AD8067 amplifier is available in a SOT-23-5 package and is

rated to operate over the industrial temperature range of –40°C

to +85°C.
