  • ADS7054: Some questions about the ADS7054 chip.

    Resolved
    Part Number: ADS7054 Tool/software: Hey team, I am a beginner in embedded systems, and I am currently working with STM32 chips to communicate with the ADS7054. However, there are some aspects of the ADS7054 chip that I don't fully understand. I have…

  • ADS7054: Common-mode question

    TI Thinks Resolved
    Part Number: ADS7054 Tool/software: The ADC is described as fully differential, but the common-mode range is tightly specified near Vref/2. Will it report, say, 1 volt input if AINP is +1.7 and AINM is +0.7? In other words, does it digitize the difference…

  • ADS7054: Decoupling AVDD pin with 3.3uF Tantalum instead of Ceramic

    Resolved
    Part Number: ADS7054 Tool/software: Dear Support, The datasheet for the ADS7054 recommends using 3.3uF capacitors for AVDD decoupling (section "AVDD and DVDD Supply Recommendations"). However, such ceramic capacitors are not suitable for MTBF calculations…

  • ADS7054: SPI Clock driven at 25MHz?

    Resolved
    Part Number: ADS7054 Hi team, My customers are interested in driving this part at 25MHz (their lab equipment allows for either 12.5Mhz or 25MHz). What would happen if the SPI clock was driven at 25MHz? This would only be done for testing purposes…

  • ADS7054: Can one input be grounded to make this a single-ended input?

    TI Thinks Resolved
    Part Number: ADS7054 Hey team, Other than losing half the dynamic range, what are the potential downsides to grounding one of these ADC inputs? And how does losing half the dynamic range affect the operation of the circuit? This is for a CT current…

  • ADS7044: Alternatives - ADS7054, ADS7047, ADS7057

    Resolved
    Part Number: ADS7044 Other Parts Discussed in Thread: ADS7054 , ADS7047 , ADS7057 Hello, We use the ADS7044 (X2SON) package currently but there is limited supply. I found the ADS7047, ADS7054, and ADS7057 which look to be pin to pin, but I wanted to…

  • RE: ADS7054: No EVM or software for ADS7054?

    Resolved
    Both EVMs have communication cards; although these communications cards are different they both have an FPGA on them. The FPGA does not do any calculations, that is done in the GUI software; the FPGAs communicate with the ADC EVM and provides large amount…

  • RE: ADS7054: Select Fully Differential Amplifier for ADC

    Resolved
    Hi Hiep Welcome to TI E2E forum ! Ideally if you drive ADS7054 using one of the applications circuit shown in the datasheet, the effective loading of the input signal source will be similar to that caused by THS4551. It is mainly because of the…
