Quesion for AD7938 Throughput rate

Dear Sir/Madam,

  In the datasheet of AD7938, Throughput rate is 1.5MSPS

  If it works in 8-channel single-ended inputs mode, Throughput rate of each channel is 1.5MSPS or (1/8)*1.5MSPS?

THANKS!

    Hi,

          The AD7938 is an 8 channel ADC, The ADC sample each channel through the multiplex and outputs the data on the data bus lines. The AD7938 outputs the conversion result for all channel at a throughput rate of 1.5MSPS. Assuming a setting the AD7938 at max throughput rate, each channel will have a 1.5MSPS/8 throughput rate.

    Regards,

    Jonathan
