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.
