5. Using NACs and NACs
Between the continuous (analog) and discrete (digital) domains, the potential user of ADCs and DACs is usually faced with three main problems: firstly, he or she must be able to interpret the specifications correctly; secondly, he or she must make the right choice; and thirdly, whether for evaluation or control purposes, he or she may have to test the converter.
In the case of data conversion products, these three tasks are particularly delicate, especially in the case of high speeds and/or high resolutions.
Specifications are not easy to interpret, because manufacturers often specify their products for simple cases, such as pure sine, whereas they are actually used for complex and/or transient signals. But even well-specified converters present difficulties, since they require mastery of both analog and digital technical domains. For these...

Using NACs and NACs
Bibliography
Software tools
On the Analog Devices Inc. website, a number of analog-to-digital and digital-to-analog simulation tools and models are available. These range from simple 'on-line' theoretical simulations on their site, to complex models that can be interfaced with tools such as Mathlab, Simulink from The MathWorks and ADS from Agilent.
Time and spectral domains are accessible.

...Standards and norms
There are standards or projects on CANs and NACs, but to my knowledge, their use is never cited by manufacturers.
This is probably due to the dynamism of manufacturers and the specificity of each market segment addressed.
Project DYNAD still has a home page on the Internet, but no changes since 2002. (SMT4-CT98-2214 2002)
