ADS5546: output code

Kailyn Chen

Part Number: ADS5546

Hello,

The datasheet didn't describe the relationship about the input voltage VS output code. For example, if the input voltage is 0.75V , what is the output code?

Below is the configuration:

Hi Kailyn,

Can you please confirm which configuration is being used. The tables look they are the different options for configuring the part. Is default being used?

Also, is the 0.75 V input a DC voltage?

Best regards,

Drew

Hi Drew，

Thank you for your reply.

The configuration is as this:

In addition, 0.75Vpp is differential signal.

Hi Kailyn,

Thank you for this information.

Are those pin assignments, that I assume correlate to the picture of the tables you sent?

Is "adcv" voltage and "adci" current?

To confirm, dfs being set to 1 denotes "offset binary"?

For the MODE pin, both description boxes say "Internal"...should one of them be "External"?

Best regards,

Drew
