ADC3421: Question about the sampling rate

Ikechukwu Anyiam

Part Number: ADC3421

Hello team,

I have two quick questions about the sampling rate for the ADC3421:

1. The max sampling rate is 25-MSPS. Since this is a four-channel device with four ADCs, does this mean that each of the four internal ADCs can sample at 25-MSPS, or would I need to divide that rate by 4?

2. Is it possible to have the internal ADCs sample at different rates? E.g. have channel A sample at 20-MSPS and have channel B sample at 15-MSPS? 

Regards,

I.K.

    HI I.K.,

    For the ADC3421, all four channels sample simultaneously and will have the same sample rate. The device does not allow for differing sample rates on different ADC channels. The maximum sample rate is 25MSPS for the ADC3421 and this is per ADC channel; so you will be able to sample at the maximum sample rate of 25 MSPS simultaneously on all four channels.

    Best,
    Mark
