  • RE: [FAQ] How do I verify that my ADS129x device is still functional?

    Resolved
    When most ADCs appear unresponsive, a few basic debugging techniques can help verify whether or not the device is still functional. Below are some basic steps to take when an ADS129x device appears unresponsive: Apply power to the device. Then probe…

  • ADS1299: Low-frequency noise when BIAS amp is used

    Part Number: ADS1299 Tool/software: Hello, I've been working on an EEG device using the ADS1299 AFE, loosely based on the OpenBCI Cyton design. The Cyton design has a custom bias drive network, one that I'm sure seems familiar to this forum now (Fig 1…

  • RE: ADS1299EEGFE-PDK: ADS1299EEGFE-PDK

    Hi Ryan, Thank you for your answer. I control the function generator to output a 10Hz, ±10mV square wave signal, as shown in the figure. You can see that there is an error of about 1.5mV, as I mentioned before. I then turn off the function generator…
