  • ADC1175: Problem when unpluging the 5V supply

    TI Thinks Resolved
    Part Number: ADC1175 Hello all, To try to save energy, I turned off the 5V supply on the ADC1175. However, through the 3V3 input supply, the ADC was generating (I do not know how) 1.9V at the 5V power rail. This 1.9V would then feed the remaining circuits…

  • RE: ADC1175-50: Output voltage are random

    Hey Amr, As Chase said you're going to want to use a MOSFET to pull down through an LED. These output drivers are not designed to drive large resistive loads. Regards, Matt

  • ADC1175-50: TSSOP 14pin DVDD > AVDD ?

    TI Thinks Resolved
    Part Number: ADC1175-50 Hi The 14pin is described "DVDD" in datasheet /PIN DESCRIPTIONS AND EQUIVALENT CIRCUITS. The 14pin is AVDD in Other figures and EVM schematics. Is it typo? Thanks Muk

  • ADC1175: Jitter problem when sampling sinewave and squarewave

    TI Thinks Resolved
    Part Number: ADC1175 Hello, I have a project that continuously sampling ADC In pin on ADC1175 20Mhz but facing a lot of jitters on waveform. I thought problem may be regarding bare wire coming from microchip's clock and connecting ADC's clock pin. And…

  • ADC1175: What is dynamic capacitance what writes in datasheet and how to get over?

    TI Thinks Resolved
    Part Number: ADC1175 Hello, I am using adc1175 20 mhz and having spike issues on my measurements and i could not manage to remove it. ADC's Vin has spikes when i drive sine wave. When i use square wave spikes take place on rising edge on waveform.…
