... The AD848 and AD849 are high speed, low power monolithic operational amplifiers. The AD848 is internally compensated so that it is stable for closed loop gains greater. The AD849 is fully decompensated and is stable at gains greater than 24. The AD848 and AD849 achieve their combination of fast ac and good dc performance by utilizing Analog Devices’ ...

... Figure 1a. AD848 Large Signal Pulse Response Figure 1b. AD848 Small Signal Pulse Response OFFSET NULLING The input voltage of the AD848 and AD849 are very low for high speed op amps, but if additional nulling is required, the circuit shown in Figure 3 can be used. For high performance circuits it is recommended that a resistor ...
