  • ADS1261: analog power supply

    Part Number: ADS1261 I have a question regarding the ADS1261 analog power supply. The minimum recommended value is 4.75 V. We are using a 5 V input and an LDO (LT3042) as the analog supply, however, it could result in voltages around 4.7 V to 4.75 V.…

  • ADS1261: Excitation frequency

    TI Thinks Resolved
    Part Number: ADS1261 Hi Dears, Can the excitation frequency of ADS1261 be set to any value? Or It changes according to the setting of sampling rate?

  • RE: ADS1261: Delta-Sigma ADC Evaluation software

    Hi Marcel Beck, Can you help explain what these last few questions are intended to help you do? Are you trying to migrate to your own custom board, or are you still using the EVM? Marcel Beck said: would you do the switching of the mux by a script and…

  • RE: ADS1261: ADS1261 non-ACX measurement on one channel while keeping ACX signal steady for another?

    Resolved
    Hi Arnie, Glad we could help One other thing to ensure is that the ACX signals are non overlapping i.e. break before make. The ADS1261 also performs this function for you, so this would be another action to perform manually -Bryan

  • ADS1261: Non-linearity in measurement error

    TI Thinks Resolved
    Part Number: ADS1261 Hi, We are carrying out resistance measurements with our ADS1261 setup using AC-excitation current on a 4-wire system and feeding the resultant voltage into the ADC of ADS1261. We are observing non-linearity in the sense that the…
