TIC12400: paralleling inputs to get more wetting current

Part Number: TIC12400

HI team, Could I connect 2 inputs each sourcing 15mA to give 30mA capability?

  • Hello Ajayt,

    This would only work in the continuous mode. In the polling mode the device will turn on the current sources individually.

    Hi as a follow up question on teh ADC

    I have a technical question with regards to the TIC12400…. You mentioned before that the ADC measures voltages from 0-6V (1024 max codes), but in the data sheet it mentions a VS Ratio bit that can be applied to increase the voltage measurement to 30Vdc – is this only for measuring the VS supply or can it be applied to the input monitor pins as well?

    Hello Ajayt,

    Yes this is correct, the scaling is only for the VS measurement.

    Regards,
    Andrew
