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.

High Speed DAC and Flash ADC Buffers
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. T he low power and small outline package of the AD847
make it very well suited for high density applications such as
multiple pole active filters.

T he AD847 represents a breakthrough in high speed amplifiers
offering superior ac & dc performance and low power, all at low
cost. T he excellent dc performance is demonstrated by its ±5 V
3. T he AD847 is internally compensated for unity gain opera-
tion and remains stable when driving any capacitive load.
