Part Number: ADS8168

Hello team,

My customer has a below question.

Can you give me explanation that how to calculate the data rate for sequential conversion with 4 differential inputs(=8ch inputs)?

Best regards,

Shotaro

    Hello Shotaro-san,

    ADS8168 supports a maximum conversion rate of 1MSPS.  Each differential channel requires two inputs, and the voltage difference between these inputs is sampled and converted in a single conversion cycle.

    Therefore, sampling 4 differential channels, the maximum conversion rate for each channel will be 1MSPS/4 = 250ksps/channel.
