... Hz) to the ultimate video amplifier, the AD811, which features 0.01% differential gain and 0.01 differential phase. APPLICATION HIGHLIGHTS buffer the AD847 offers a full-power bandwidth of 12.7 MHz (5 V p-p with 5 V supplies) making it outstand- 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 multiple pole active filters ...

... OFFSET NULLING The input offset voltage of the AD847 is very low for a high speed op amp, but if additional nulling is required, the circuit shown in Figure 21 can be used. Figure 21. Offset Nulling INPUT CONSIDERATIONS An input resistor (R in Figure 20) is required in circuits where IN the input to the AD847 will be subjected to transient or con- tinuous overload voltages exceeding the 6 V maximum differ- ential limit ...

... AD847 HIGH SPEED DAC BUFFER The wide bandwidth and fast settling time of the AD847 makes it a very good output buffer for high speed current-output D/A converters like the AD668. As shown in Figure 27, the op amp establishes a summing node at ground for the DAC output. The output voltage is determined by the amplifier’ ...
