APPLICATIONS
Professional video
The AD8000 power-down mode reduces the supply current to
High speed instrumentation
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 (40C to +125C).
CCD imaging
A triple version of the AD8000 (AD8003) is underdevelopment.

feedback amplifier. Using Analog Devices, Inc., proprietary
eXtra Fast Complementary Bipolar (XFCB) process, the ampli-

AD8000 can drive over 100 mA of load current with minimal
5
distortion. The amplifier can operate on +5 V to 6 V. These
6
specifications make the AD8000 ideal for a variety of applica-
7
tions, including high speed instrumentation.
