ADS7871: ADS7871 no data on DOUT pin

Wouter Kragt

Part Number: ADS7871

Hi team,

A customer is testing the ADS7871 and has a question on how to drive it.

According to the DS it should work. However, they are not receiving any data on the DOUT pin, the pin connections are shown in the figure below.

How do they configure the AD converter so that data comes from the AD converter?

Can you supply me with an example code in C?

Thank you.

Kind regards,

Wouter Kragt

Hi Wouter,

There is a Linux driver under the tool folder for the ADS7871, that is the only example code we have to offer. Please post a screen shot of the control signals that you are applying to the ADS7871 device (/CS, SCLK, DIN minimum).
