specifications which include an open-loop gain of 3500 V/V
(500
Ω
load) and low input offset voltage of 0.5 mV. Common-
mode rejection is a minimum of 78 dB. Output voltage swing is
±
3 V into loads as low as 150
Ω.
Analog Devices also offers
over 30 other high speed amplifiers from the low noise AD829
(1.7 nV/√Hz) to the ultimate video amplifier, the AD811, which
features 0.01% differential gain and 0.01° differential phase.
APPLICATION HIGHLIGHTS
1. As a buffer the AD847 offers a full-power bandwidth of
12.7 MHz (5 V p-p with
±
5 V supplies) making it outstand-
ing as an input buffer for flash A/D converters.
2. The low power and small outline package of the AD847
make it very well suited for high density applications such as
multiple pole active filters.
3. The AD847 is internally compensated for unity gain opera-
tion and remains stable when driving any capacitive load.
PRODUCT DESCRIPTION
The AD847 represents a breakthrough in high speed amplifiers
offering superior ac & dc performance and low power, all at low
cost. The excellent dc performance is demonstrated by its

Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only, and functional
operation of the device at these or any other conditions above those indicated in
the operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

ESD SUSCEPTIBILITY
ESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 4000 volts, which readily accumulate on the
human body and on test equipment, can discharge without de-
tection. Although the AD847 features proprietary ESD protec-
tion circuitry, permanent damage may still occur on these
devices if they are subjected to high energy electrostatic dis-
charges. Therefore, proper ESD precautions are recommended
to avoid any performance degradation or loss of functionality.
