HA5340/883
High Speed, Low Distortion, Precision Monolithic
Sample and Hold Amplifier
Description
The HA-5340/883 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 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.
