  • ADS127L11: Threshold voltage of Digital In

    Resolved
    Part Number: ADS127L11 Hi team, How much is the digital input threshold voltage? I can only see the data below in the datasheet. What will the logic become when input 0.3*IOVDD~0.7*IOVDD? Best regards, Yuto

  • ADS127L11: RESET / SCLK timing for td(RSSC)

    TI Thinks Resolved
    Part Number: ADS127L11 Hi team, I got question about RESET / SCLK timing for td(RSSC). As shown in Figure 6-3 in D/S, do we need to keep SCLK "Low" while td(RSSC) timing? Or td(RSSC) is just a time that the communication has not started, thus…

  • RE: ADS127L11 + INA128 Schematic Review

    Hello Lajos, I checked your schematic and have a few comments. 1. Pinout and connections around ADS127L11 are correct and should work with no issues. 2. The reference circuit should work well as long as the reference pre-charge buffer is enabled in each…

  • ADS127L11: SPI Operation about CLK/SCLK

    Resolved
    Part Number: ADS127L11 Hi team, I got a question about SPI Operation in D/S 9.1.1. It says that: 1. Use an SCLK that is phase coherent to CLK; that is, ratios of 2:1, 1:1, 1:2, 1:4, and so on. 2. Minimize phase skew between SCLK and CLK (< 5 ns). …

  • ADS127L11: Internal vs External Clock

    Resolved
    Part Number: ADS127L11 As I'm working through the ADS127L11EVM-PDK, I see the 127 has some different clock options. From the data sheet: Simply from a parts reduction/cost reduction/EMI standpoint, not having another oscillator on our board is appealing…

  • ADS127L11: AVDD1 3Ohm vs 3.3Ohm resistor value

    Resolved
    Part Number: ADS127L11 Hi all My customer is evaluating the ADS127L11 and they find that for the AVDD1 supply a 3Ohm resistor is required (page 42 of the datasheet). As 3Ohm is not a standard value: They plan on using a 3.3Ohm 1% TK100 0603 thickfilm resistor…
