  • ADS1247: The need of a series resistance for IEXC1/2

    TI Thinks Resolved
    Part Number: ADS1247 Tool/software: I am currently testing ADS1x48EVM with a PT1000 resistor in a ratiometric configuration, and see that they have placed a 680 ohm series resistance in the IEXC current loop. (See picture) Can someone explain me why this…

  • ADS1247: When using ADS1247 to read 10K NTC temperature sensor ADC, there will be a cycle fluctuation of about 10 seconds

    Part Number: ADS1247 Tool/software: Read a 10 KNTC temperature sensor and configure a 39K sampling resistor for periodic fluctuations at room temperature. Using an external reference voltage source, a 50uA current source, PGA = 1, and DR =80SPS, there…

  • ADS1247: START and SYNC Commands

    TI Thinks Resolved
    Part Number: ADS1247 Tool/software: I am trying to optimize current by keeping only enabling START high only when necessary. I am not using DRDY just waiting the appropriate time after START to read the data as per the sampling rate. I am not sure how…
