TINA/Spice/ADC161S626: Question about output wave shape of ADC ADC161S626

Hi guys,

I am now using ADC161S626 to test the output wave shape of ADC ADC161S626, but I meet some problems:

1, The output wave shape of ADC161S626 does not show the full input sine wave. Could you please tell me what causes this problem and how to solve it?

2, Is there any ADC model which I could get output wave shape directly instead of connecting a DAC?

Thank you!ADC161S626.TSC

I think you post similar question as this one as shown here: http://e2e.ti.com/support/development_tools/webench_design_center/f/234/p/652190/2395488#2395488

Please confirm. If this is the case, I will close one of these. Thanks.

An ADC generates a bit stream, if you need to visulize the output code or reconstruct the input to the ADC, you can attach a DAC to convert the output bits to an analog signal.
The constructed waveform deponds on the number of bits and Vref used.
Kind Regards,
