Simulation of ADC used in measurements

Hi all

Need suggestions I wanted to check the simulation for voltage ADC which is used in high precision and accurate value. I am using maximum 10 v, need to know simple schematic on which I can run and test the simulation ?

Ideal ADC returns quantized values that you can normally simulate with integer numbers. For example a two's complement 16 bit ADC can be simulated using I16 values in LabVIEW. However this will only show the effect of quantization, is that enough for you.

 

Depending on how accurate a model you want to create you need to  know the exact behavior of your ADC, that is parameters like Integral/Differential Non Linearity (INL and DNL) and other physical characteristics like DC-Offset, noise level...

 

What is it you try to achieve? How many bits do you have? Is an ideal ADC model enough for you?

I'm confused by the words "simulation" (which suggests, to me, a computer model of a device) and "schematic" (which suggests, to me, physical hardware and using computer to measure the resulting data).  Can you describe a bit more clearly what you want to do?  Feel free to describe not only one Voltage number, but a voltage range and some idea of sampling frequency, number of points, etc.
