INA200: about OFFSET VOLTAGE Threshold

Part Number: INA200

Hi,

Could you tell me about INA200 comparator threshold voltage?
I got two questions from customers.
Please check the attached document.

INA200.pdf

1.Which is correct the detection voltage Page 6 Threshold and Figure1 voltage?
2.Please tell me the difference between trip point and threshold.
   Customer wants to know the values of H→L and L→H threshold.

Best Regards,
Yusuke/Japan Disty

  • Hello Yusuke-san,

    For your first question, the values in the table on Page 6 show the typical value for the threshold (along with the min and max values), while the values in Figure 1 are example values used to show the typical comparator hysteresis.

    For your second question, Trip Point and Threshold mean the same thing for this application and are used interchangeably.
  • Mitch-san,

    Thank you for your kind support.
    I understood your information.

    I would like to ask a question additionally.
    Could you tell me the lot sampling data of Hysteresis?
    Customer want to know the variation information of the threshold for the application design.

  • Hello Yusuke-san,

    I am looking to see if we have this information available, I will let you know when I find out.
  • Mitch-san,

    Thank you for dealing with this matter.
    I look forward to your reply.

  • Hello Yusuke-san,

    We can’t share the original characterization data for hysteresis, but the methodology is to take a small but statistically significant number of units and measure them to come up with our typical numbers. In this case, it’s not tested on each device in the factory and is a typical number only.

    Threshold is tested at production on each device against the data sheet limits with some margin for variation and capability. We are not allowed to share that information but we can say that it can and does vary by device and lot.
