Application Notes

Great care should be taken in the board layout to minimize

ground loop and similar “hidden resistor” problems, as well

as to minimize digital signal feedthrough. A suitable layout

for the immediate vicinity of the ICL7134 is shown in Figure

18, and may be used as a guide.

Some applications bulletins that may be found useful are

listed here:

A002 “Principles of Data Acquisition and Conversion”

A018 “Do’s and Don’ts of Applying A/D Converters”, by

Peter Bradshaw and Skip Osgood.

A020 “A Cookbook Approach to High Speed Data

Acquisition and Microprocessor Interfacing,”, by Ed

Sliger.

A042 “Interpretation of Data Converters Accuracy

Specifications”

R005 “Interfacing Data Converters & Microprocessor”, by

Peter Bradshaw et al., Electronics, Dec 9, 1976.

Most of these are avilable in the Intersil Data Acquisition

Handbook, together with other material.
