    TI Thinks Resolved
    Part Number: ADS1198 Hello, My previous forum has been locked and no one was able to figure out what I'm experiencing. I am experiencing anomalous behavior on multiple ADS1198 devices on the same PCB. Some details about the setup: I have 4 ADS1198…

  • ADS1198: Frequently 1 ADC code sample glitch in data on custom PCB with ADS1198

    TI Thinks Resolved
    Part Number: ADS1198 I'm seeing a small issue in the data on our custom PCB and wanted to get your review. Raw ADC data occasionally changes by 1 ADC code for a single sample e.g.: 15, 15, 15, 14, 15 This creates a visible spike or glitch in the…

  • ADS1198: Anomalous behavior on CH3/CH4 across multiple ADS1198

    Part Number: ADS1198 Hello, I am experiencing anomalous behavior on multiple ADS1198 devices on the same PCB. Some details about the setup: I have 4 ADS1198 in BGA package connected in cascade, with 4 separate chip select lines and a shared SPI…
