ADS7049-Q1: When ADS7049 is not collecting data, there will be a slowly rising waveform

Part Number: ADS7049-Q1

Hi Team,

When ADS7049 is not collecting data, there will be a slowly rising waveform. What is the reason?

The yellow is clk, the blue is sdo

  • Hello Amelie,

    When you say "not collecting data", do you mean that CS is high the entire time? If not, can you elaborate? Does the device perform as expected when collecting data?

    Looking at the schematic, is there anything else connected to SDO or is the ADS7049 the only device on the bus?

    Regards,
