The excellent dc performance is demonstrated by its 5 VOLTAGE VoltsQUIESCENT CURRENT mAQuiescent Current vs. Supply Voltagespecifications which include an open-loop gain of 3500 V/V(500 load) and low input offset voltage of mV.

3 Common-mode rejection is a minimum of 78 dB. Output voltage swing is 3 V into loads as low as 150 . Analog Devices also offersover 30 other high speed amplifiers from the low noise AD829( nV/ Hz) to the ultimate video amplifier, the AD811, whichfeatures differential gain and differential HIGHLIGHTS1. As a buffer the AD847 offers a full- Power bandwidth MHz (5 V p-p with 5 V supplies) making it outstand-ing as an input buffer for flash A/D The low Power and small outline package of the AD847make it very well suited for high density applications such asmultiple pole active The AD847 is internally compensated for unity gain opera-tion and remains stable when driving any capacitive Driving Capacitive LoadsAD847 SPECIFICATIONSREV.

Electrostaticcharges as high as 4000 volts, which readily accumulate on thehuman body and on test equipment, can discharge without de-tection.

8 Although the AD847 features proprietary ESD protec-tion circuitry, permanent damage may still occur on thesedevices if they are subjected to high energy electrostatic dis-charges.
