  • RE: ADS1260: Internal/External Reference configuration

    Resolved
    Hi Kuramochi, The reference's characteristic depends on its design. The followings show the setting time of internal voltage reference on the ADS1260 and the settling time of external voltage reference REF6025 which has a higher BW buffer on the output…

  • RE: ADS1261EVM: ADS1260 : Need to measure uA current ADC solution

    Hi Jax, This is very good work, you are using these tools very effectively! You have confirmed that the input signal will be within the input range of the amplifier inside the ADS1261. To answer your question about the VREF voltage: the ADC will need…
