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.
