ADC input pin protection

Hi, many of my customer is using TVS diode to limit the ADC pin of C2000 MCU within 0-3.3V. I know we have circuit protection for communication interface such as 485, CAN. But I'm not sure if we have any suitable and cost competitive devices for the protection like ADC pin of MCU.

Thanks.

  • Howard-

    Is your customer using the TVS diode for ESD protection, surge protection, or DC overvoltage protection? If it is ESD we have a number of solutions like the TPD1E1B04 that should work. If surge protection or some DC overvoltage protection is necessary, the TVS0500 can provide protection on the line. If you can provide some more details about what the test requirements are, I'd be happy to recommend a more specific part.

    Thanks,

    Alec
