GENERAL DESCRIPTION
The AD8000 is an ultrahigh speed, high performance, current
feedback amplifier. Using ADI’s proprietary eXtra Fast Com-
plementary Bipolar (XFCB) process, the amplifier can achieve a
small signal bandwidth of 1.5 GHz and a slew rate of 4100 V/µs.
The AD8000 has low spurious-free dynamic range (SFDR) of
75 dBc @ 20 MHz and input voltage noise of 1.6 nV/√Hz. The
AD8000 can drive over 100 mA of load current with minimal
distortion. The amplifier can operate on +5 V to ±6 V. These
specifications make the AD8000 ideal for a variety of applica-
tions, including high speed instrumentation.
With a differential gain of 0.02%, differential phase of 0.01°, and
0.1 dB flatness out to 170 MHz, the AD8000 has excellent video
specifications, which ensure that even the most demanding
video systems maintain excellent fidelity.

The AD8000 power-down mode reduces the supply current to
1.3 mA. The amplifier is available in a tiny 8-lead LFCSP pack-
age, as well as in an 8-lead SOIC package. The AD8000 is rated
to work over the extended industrial temperature range (−40°C
to +125°C). A triple version of the AD8000 (AD8003) is under-
development.
