As a buffer the AD847 offers a full-power bandwidth of High Speed Cable Driver 12.7 MHz (5 V p-p with 5 V supplies) making it outstand- High Speed DAC and Flash ADC Buffers ing as an input buffer for flash A/D converters. 2. The low power and small outline package of the AD847 make it very well suited for high density applications such as PRODUCT DESCRIPTION multiple pole active filters. The AD847 represents a breakthrough in high speed amplifiers offering superior ac & dc performance and low power, all at low 3. The AD847 is internally compensated for unity gain opera- cost. The excellent dc performance is demonstrated by its 5 V tion and remains stable when driving any capacitive load. 6 5.5 5 4.5 4 025 10 150 SUPPLY VOLTAGE Volts Quiescent Current vs. Supply Voltage AD847 Driving Capacitive Loads REV.
