  • ADS131M04: How can I find SNR @gain = 8?

    Resolved
    Part Number: ADS131M04 I have checked on ADS131M04's data sheet. But it has SNR value only at gain = 1 and 64. So what is exact number of SNR @gain = 8 and how can I find this number?

  • ADS131M04: Data sheet Figure 81 through 84

    Resolved
    Part Number: ADS131M04 I have tried a couple of PDF readers before asking if the Figures 81 through 84 are identical in the datasheet version "SBAS890A–MARCH 2019–REVISED JULY 2019". I am on Alert Me if the datasheet is revised. Thank you

  • RE: Compiler/ADS131M04: CODE C exemple

    Resolved
    Hi Nasri, FYI: I found a bug in the ADS131M04 Example C Code that I would like to make you aware of... In the "ads131m0x.h" file there is a defined macro for "WLENGTH" on line 1665. This macro had an incorrect register address, and should be changed…

  • ADS131M04: Do you have any graph which shows relation between CLKIN jitter and SNR?

    TI Thinks Resolved
    Part Number: ADS131M04 Hello guys, One of my customers is considering using ADS131M04 for their new products. They want to use MSP430 clock output (8MHz) as ADS131M04 CLKIN. But the clockoutput has about +/-3% jitter. So they want to know how much…

  • ADS131M04: We are using this converter to retrieve the dc voltage from the external feed, by blocking the capacitor

    Resolved
    Part Number: ADS131M04 For our experimentation we are removing the block DC option since we have to acquire the direct voltage, Is that is the right way to get the voltage from the sensors? / How exactly we should configure the converter to acquire…

  • ADS131M04: Questions : (1)Input ratings at gain setting > 8, (2) 16bit output mode

    Part Number: ADS131M04 Hi team, I I have two questions for ADS131M04 as below. 1. When the gain of PGA >8, the recommended operating input voltage is AVDD-1.8V, while it is AVDD at PGA gain <4. What is the negative impact when >AVDD-1.8V applied…

  • ADS131M04: Reading the internal register when the ADCs are running is not always successful, stopping the ADCs either by clearing the CHx_EN bits in CLOCK register or by sending STANDBY command fixes the problem.

    TI Thinks Resolved
    Part Number: ADS131M04 Hi, when I read back the configuration registers (always in single SPI transactions with 6 x 24 bit words in a frame) in the ADC chip, I get sometimes (in roughly 10% of the cases) the status word (0x050f or 0x0500) instead of…
