High amplitude, high frequency signals can be sampled with very low distortion being introduced. The combination of exceptionally fast acquisition time and specified/characterized hold mode distortion is an industry first. Additionally, the AC performance is only minimally affected by additional hold capacitance. To achieve this level of performance, the benefits of an integrating output stage have been combined with the advantages of a buffered hold capacitor. To the user this translates to a front-end stage that has high bandwidth due to charging only a small capacitive load and an output stage with constant pedestal error which can be nulled out using the offset adjust pins. Since the performance penalty for additional hold capacitance is low, the designer can further minimize pedestal error and droop rate without sacrificing speed. Low distortion, fast acquisition, and low droop rate are the result, making the HA-5340/883 the obvious choice for high speed, high accuracy sampling systems.
