Dear Technical Support Team,
My target sampling rate is 250kSPS with simultaneous.
According to the datasheet of ADS9815, 1MSPS/channel.
If ADC's max sampling rate is 1MSPS, I guess that 250kSPS/ch with sequential 4:1 mux switching and it behaves like 250ksps simultaneouslly.
Or Even when sequential 4:1 mux switching, does ADS9815 work 1MSPS/channel?
Best Regards,
ttd
Hi ttd,
Thanks for your question!
ADS9815 samples two channels simultaneously at a time. Channels 1 and 8 are sampled together, each at 1MSPS. Then, channels 2 and 7 are sampled together. Then, channel 3 and 6 and then, channels 4 and 5. All 8 channels will sample at 1MSPS. Please let me know if you have any further questions or need any assistance with a schematic or layout review.
Best regards,
Samiha
