specifications which include an open-loop gain of 3500 V/V (500 Ω load) and low input offset voltage of 0.5 mV. Commonmode 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 with ± 5 V supplies) making it outstanding as an input buffer for flash A/D converters.
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 ± 5 V
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 operation and remains stable when driving any capacitive load.
