Footnotes:

➀ Full Scale (FS) = 10V. Full Scale Range (FSR) = 20V.

➁ Sample-to-hold offset error (pedestal) is constant regardless of input/output level.

Technical Notes

1.

All ground pins should be tied together and connected to system analog ground

as close to the package as possible. It is recommended to use a ground plane

under the device and solder ground pins directly to it. Take care to ensure that

no ground potentials can exist between ground pins.

2.

External 0.1μF to 4.7μF tantalum bypass capacitors are required in critical

applications.

3.

A logic 1 on S/H puts the unit in the sample mode. A logic 0 puts the unit in hold

mode.

4.

The maximum capacitive load to avoid oscillation is typically 250pF. Recom-

mended resistive load is 500Ω, although values as low as 250Ω may be used.

Acquisition and sample-to-hold settling times are relatively unaffected by

resistive loads down to 250Ω and capacitive loads up to 50pF. Greater load

capacitances will affect both acquisition and settling time.

5.

Gain and offset adjusting can be accomplished using the external circuitry

shown in Figure 2. Adjust offset with a 0V input. Adjust gain with a ±FS input.

Adjust so that the output in the hold mode matches the input.
