  • ADS131E08: Why is Vpp much larger than 6.6 times Vrms

    TI Thinks Resolved
    Part Number: ADS131E08 Hi team, Customer test the EVM and internal short input. The noise result is shown as below. Vpp is much larger than 6.6 times Vrms. Could you pls help me understand the reason? And any suggestion that can improve Vpp of noise? …

  • RE: ADS131E08: Nosie measurement

    Hi Rayna, One more thing I forgot in my previous post. An Offset voltage is seen on each channel, so it's good for the customer to do offset and gain calibration. Best regards, Dale

  • ADS131E08: Full scale range

    Part Number: ADS131E08 Hi, can I check what is the full scale range of the ADS131E08 when AVDD = 5V and AVSS = 0V and a PGA of 12 is applied? Based on the datasheet, the differential input voltage = +-VREF/Gain. In which case, for VREF = 2.5V and Gain…
