Low Cost, 80 MHz FastFET™ Op Amps

FastFETs are an entirely new class of amplifiers from Analog Devices, of which the AD8034 and AD8065 are the first two parts to be released. FastFETs combine the desirable specs of FET input amps (high input impedance that almost eliminates the need to consider the input bias current in designs) with those of ADI's proprietary XFCB technology (most especially low power consumption, low noise and distortions, and a wide supply voltage). We believe FastFETs will change the way designers think about amplifiers in general, and FET amps specifically.

Certainly any designers currently using FETs will certainly be interested in a high-performance and high-speed FET amp that uses a fraction of the power, in packages as small as SC-70.
