  • ADS7067: ADS7067 - tD_CKDO and Enhanced SPI

    TI Thinks Resolved
    Part Number: ADS7067 Can you please help us achieve the maximum sample rate on this chip. tD_CKDO is defined as "Delay time: SCLK launch edge to (next) data valid on SDO: 16 ns max". When we observe the oscilloscope on SPI mode 00, we see effectively…

  • ADS7067: ADS7067- Enhanced SPI

    Part Number: ADS7067 Other Parts Discussed in Thread: TLA2518 The datasheet of the ADS7067 mentions the following: The enhanced-SPI enables the ADS7067 in achieving high throughput at lower clock speeds. And under 7.3.10.1 is mentioned: The device features…

  • ADS7067: ADS7067 reading on a few channels are incorrect

    Part Number: ADS7067 Other Parts Discussed in Thread: ADS7066 Hi there, We are using the TI ads7067 in our custom board but a few of the channels (CH2, CH4, and CH6) are often reporting voltage under the measured value. We have an oscilloscope monitoring…

  • ADS7067: tD_CKDO: launch & capture edge

    TI Thinks Resolved
    Part Number: ADS7067 In a previous post the tD_CKDO (max 16ns) spec in combination with high samplerate/SPI CLK freq was discussed. Link to post: https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1613870/ads7067…

  • ADS7067: Input leakage current at analog inputs

    Resolved
    Part Number: ADS7067 Other Parts Discussed in Thread: OPA325 Hi, we use the ADS7067 in one of our applications. For the most connected analog signals we use the OPA325 as input buffer, but for some slow changing (nearly constant) signals we simply use…

  • ADS7067: Power supply for AVDD and DVDD

    Resolved
    Part Number: ADS7067 Tool/software: Dear Team, Do I need to use separate LDO's for AVDD and DVDD rails. Or Can I use a single LDO for powering the AVDD and DVDD rails. Regards HARI

  • ADS7067: Quiet time / conversion time cannot be met together - are they related / exchangeable in on the fly mode?

    Part Number: ADS7067 Other Parts Discussed in Thread: ADS7066 Hi, when we apply max sampling rate (800kHz) at 50MHz SPI in on the fly mode without averaging the timings globally cannot be met formally. Do we expect too much from the component? (e.g…

  • ADS7067: ADS7067

    Part Number: ADS7067 Dear all, where can I find a RTL simulation model for the ADS7067 chip? Thanks Marco

  • ADS7067: Auto-sequence SDO Data number of clocks

    Part Number: ADS7067 Tool/software: In the SBASA78B – MARCH 2021 – REVISED SEPTEMBER 2024 datasheet/documentation for the AD7067 the section 6.4.4 Auto-Sequence Mode contains diagram "Figure 6-15. Starting Conversion and Reading Data in Auto-Sequence…
