700ns, Low Distortion, Precision Sample

and Hold Ampliﬁer

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

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 the obvious choice for high

speed, high accuracy sampling systems. For a Military

temperature range version request the HA-5340/883 data

sheet.
