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.
