DAC71416: Short circuit current

Michele Abolaffio
Prodigy 20 points
Part Number: DAC71416

Tool/software:

I would like to ask clarification about the short-circuit current and protection that I found in the datasheet:
What happens when I short a DAC output to Ground?

Does a protection kick in, and can it stay shorted indefinitely?

    Hi,

    The DAC output will attempt to sink current and hit a typical value of around 40 mA.

    The DAC71416 does have a Thermal Shutdown that will disable all DAC outputs in the event that the Die Temperature reaches 140°C.
    If the DAC doesn't reach this temperature, it will likely stay shorted indefinitely.

    Thanks,
    Lucas
