1.3 mA. The amplifier is available in a tiny 8-lead LFCSP package,
Video switching
as well as in an 8-lead SOIC package. The AD8000 is rated to work
IF/RF gain stage
over the extended industrial temperature range (−40°C to +125°C).

A triple version of the AD8000 (AD8003) is underdevelopment.
GENERAL DESCRIPTION 3 VS =

5V
The AD8000 is an ultrahigh speed, high performance, current
2 RL = 150 VOUT = 2V p-p
feedback amplifier. Using Analog Devices, Inc., proprietary

rate of 4100 V/μs.
GAIN (dB) D –2
The AD8000 has low spurious-free dynamic range (SFDR) of
–3 G = +2, R
75 dBc at 20 MHz and input voltage noise of 1.6 nV/√Hz. The
F = 432 –4 NORMALIZE
AD8000 can drive over 100 mA of load current with minimal

distortion. The amplifier can operate on +5 V to ±6 V. These
–6
specifications make the AD8000 ideal for a variety of applica- tions, including high speed instrumentation.
