Other Parts Discussed in Thread: ADS1259

Does anyone know, how to check whether the IC ADS1259 (ADC) is working or not?

    Hi Sampada,

    Welcome to our e2e forum! What sort of issues are you having with the ADS1259? Are you using it with our EVM and having trouble or is the ADS1259 mounted to your own hardware?

    Hi Sampada,

    If the ADS1259 is powered, clocked, and GPIOs set to run (START = /PWDN = HIGH, then you should be able to probe the /DRDY pin to see if it is pulsing.

    "/DRDY" is a kind of "heart beat" that you can look at to quickly check if the device is active. If you don't see this signal, then double check the conditions mentioned above.

    Best regards,
    Chris
