The Typical Characteristics help the designer pick a recommended RS versus capacitive load. The resulting frequency response curves show a flat response for several selected capacitive loads and recommended RS combinations. Parasitic capacitive loads greater than 2pF can begin to degrade the performance of the OPA847. Long PCB traces, unmatched cables, and connections to multiple devices can easily cause this value to be exceeded. Always consider this effect carefully and add the recommended series resistor as close as possible to the OPA847 output pin (see the Board Layout section)
