REF5025: Question about REF5025 output Voltage Accuracy vs Temperature graph.

Part Number: REF5025

Tool/software:

Hello guys,

One of my customers is considering using REF5025A(Standard grade) for their new products.
At this moment, they have the following questions.
Could you please give me your reply?

Q1.
Does Figure7-4, Output Voltage Accuracy vs Temperature graph show the characteristics of REF5025(High grade)? Or REF5025A(Standard grade)?

Q2.
If the answer to Q1 is REF5025(High grade), do you have the output Voltage Accuracy vs Temperature graph of REF5025A(Standard grade)?

Q3.
If the answer to Q2 is No, Does REF5025A have similar output accuracy change trend with REF5025 though the accuracy level would be different from REF5025?

Your reply would be much appreciated.

Best regards,
Kazuya.

    Hello Kazuya,

    Figure 7-4 is the typical temperature drift for either grade of REF50, not the maximum. The trend should be similar for both grades. It is meant to be used as a guideline of how the output voltage may change with temperature. For the maximum values, please refer to the 8 ppm/°C for the standard grade, as specified in the electrical characteristics table, as this is what we guarantee.

    Thanks,

    Jackson
