AD847 High Speed Op-Amp

AD847 op-amp 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 specifications which include an open-loop gain of 3500 V/V (500 W 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 W. Analog Devices also offers over 30 other high speed amplifiers from the low noise AD829 (1.7 nV/ÖHz) to the ultimate video amplifier, the AD811, which features 0.01% differential gain and 0.01° differential phase.

Applications of AD847 Op-amp

• As a buffer the AD847 offers a full-power bandwidth of 12.7 MHz (5 V p-p with ±5 V supplies) making it outstanding as an input buffer for flash A/D converters.

• 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.

• The AD847 is internally compensated for unity gain operation and remains stable when driving any capacitive load.
