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 ±5 V 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.
