Tool/software:
Dear Technical Support Team,
When I checked the operation of this ADC, I input a synthesizer (sine wave),
As shown in the attached graph ③, there is a bias of a certain period of about 18 cycles for the resolution of 12-bit ADC.
I connected this synthesizer to another measuring instrument (oscilloscope), but this symptom did not occur.
Is there any cause of this symptom or any register that can correct it?
For reference (See attached file)
① sine wave obtained by ADC12DJ3200
② histogram of ①.
③ histogram of ② with the area around 2048 enlarged
Best Regards,

HI TTD,
Please send us a block diagram with details on your measurement.
Lets start there first, this will help us better understand.
Thanks,
Rob
