Series voltage reference solution

Hi Team,

I got an inquiry from one of my customers looking for a series voltage reference to replace the MAX6043AAUT33#TG16 

Below are the critical parameters: 

Temperature stability – 15ppm/C

Initial Accuracy – 0.06%

Supply voltage – 12 V or higher

Low Noise: 4uVp-p at 2.5V output

Operating temp - -40 to 125C

I did try to look for a voltage reference solution similar to the maxim part but it seems like I can't find a solution with greater than 12 V Vin and with low temperature coefficient and low noise. 

Please do let me know if I have missed one or if we do have anything in the roadmap. 

Thanks! 

Regards, 

Alfred

  • Hello Alfred,

  • Hi Alfred

    For above mentioned specification you can consider REF50xx voltage reference. Specifications are

    Temperature stability – 3ppm/C (High grade part)

                                      -  8ppm/C (standard grade part)

    Initial Accuracy – 0.05%

    Supply voltage –  Up to 18V max

    Low Noise: 3uVpp/V. So for 2.5V version it would be around 7.5uVpp

    Operating temp - -40 to 125C

    Package: SOIC-8 and MSOP-8 (Maxim MAX6043 has SOT-23 package)

    Please let me know if you need additional information from my side

    Thanks & Regards
