ADS8331: ADS8331 - SPI Interface: Does DOUT goes to High-Impedance when /CS=1

Antonio Mollfulleda22

Part Number: ADS8331

Regarding the SPI interface, in the datasheet it is not explicitly mentioned that DOUT signal goes to a high-impedance state when /CS is high.

Can someone confirm or reject the behavior?

Thanks

Hi Antonio,

Yes, SDO will go to high impedance when CS is high. Fig 1, page 12 shows an example of timing configuration when reading data while sampling; with SDO High-Z while CS is high.

Thank you,

Best Regards,

Luis

Thanks. I didn't realize on this figure.
