Hi Thomasx, At present there are no ADC models available in EasyEDA. This post gives a little more background: https://easyeda.com/forum/topic/MCP3008_simulation_model-LlfxrJpjB Instead of a model for a specific converter you may be able to use an array of PWL voltage sources each generating a series of 1V and 0V steps to represent a pattern of ones and zeroes as the parallel output from an ADC. Having an ADC model rather begs the question of what the output of an ADC going to be fed into? Whilst it is possible to model digital circuits in EasyEDA the modelling of anything more complex than things like counters and shift registers rapidly becomes very unwieldy and is probably more effectively done by different tools.

Hi, It is great how fast I receice a respond to me questions!!! Many thanks, good Job. Kind regards thomasx
