SUMMARY

It is not possible to use an A/D converter as a D/A converter or vice versa due to fundamental differences in their design and functionality. A successive approximation ADC, which includes a DAC as part of its architecture, highlights the distinct roles these converters play. Specifically, an ADC requires components like a sample-and-hold stage that a DAC lacks. Therefore, attempting to operate these devices interchangeably is not feasible.

PREREQUISITES
  • Understanding of A/D and D/A converter architectures
  • Familiarity with successive approximation ADCs
  • Knowledge of signal processing concepts
  • Basic electronics principles related to digital-to-analog and analog-to-digital conversion
NEXT STEPS
  • Research the architecture of successive approximation A/D converters
  • Explore the differences between A/D and D/A converters in detail
  • Learn about sample-and-hold circuits and their role in ADCs
  • Investigate applications of A/D and D/A converters in modern electronics
USEFUL FOR

Electronics engineers, signal processing specialists, and students studying digital signal conversion will benefit from this discussion.

can we use a same A/D converter as a D/A converter or vice-versa. and which type of converter can be used in that. is it possible to do so.

A successive approximation ADC contains a DAC. Look up successive approximation A/D converters for more into.
 
And, in general, no, you cannot use an ADC as a DAC, or vice versa. You can't simply run a chip "backwards." After all, the DAC is missing some of the baisc components of an ADC, like a sample-and-hold stage.
