Hi, I see mention of switching spikes with the MP4816 device of around 15mV. However, I am seeing much larger spikes of the order of 300-400 mV. Any idea what might be causing this excessive spike voltage and what I could do to fix the problem? Thanks.
Hi Marcus,
Thank you for utilizing the MPS technical Forum!
To better assist you with your question, can you please confirm:
- if 300-400mV spikes occurs using our Test Circuit 7 illustrated in the data sheet? and
- if the issue persists when you up the output resistance to a slightly higher value > 50ohms.
During the high voltage transmission, how many cycles are you sending per burst through the analog switches? Are you able to provide scope captures?
Kind Regards,
Nouman
