700ns, Low Distortion, Precision Sample
and Hold Ampli鏗乪r
The HA-5340 combines the advantages of two sample/ hold
architectures to create a new generation of monolithic
sample/hold. High amplitude, high frequency signals can be
sampled with very low distortion being introduced. The
combination of exceptionally fast acquisition time and
speci鏗乪d/characterized hold mode distortion is an industry
鏗乺st. 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 the obvious choice for high
speed, high accuracy sampling systems. For a Military
temperature range version request the HA-5340/883 data
sheet.
