  • RE: ADS1220: Reference monitor random outlier

    Hi Bob, thank you for your effort. Sorry for the late reply. I was busy with other stuff in the last weeks. Yes, right. Both ( AVDD-AVSS) and (REFP-REFN) are 2.5V. Generated by a TPS7A20 with a 1uF and 100nF decoupling cap right next to the AVDD input. AVDD…

  • ADS1220: enable PGA, read temperature not accuracy,

    Part Number: ADS1220 Hi TI expert, we use ADS1220 for temperature monitor, now, we meet some problem as below: 1. disable PGA, read temperature is accuracy, which is about accuracy and about 15.2246mv 2. enable PGA, read temperature again, which is not…

  • RE: ADS1220: ADS1220 measurement accuracy

    Hi Hale, Art has changed responsibilities within TI so I will attempt to answer. You have asked about the input current and Art gave the answer in his last post. Please review the ADS1220 figures 15 through 20 in the datasheet on page 12. These graphs…
