LOAD
specifications which include an open-loop gain of 3500 V/V
(500
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 . 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.
