ADS131M06: ADS131M06 REFIN output drive ability

Part Number: ADS131M06

Hi team,

   could you help to confirm whether our device could support REFIN to supply out side 1.2V application?

   if yes, what is the drive ability? and any note for the application?

  • Hello Shuang,

    Thank you for your post.

    The current drive capability of the internal reference is limited to only a couple hundred microamps. We do not give a specification since we do not intend for this reference to be directly loaded by any external circuitry, besides a decoupling capacitor. If the 1.2-V reference is to be used by an external circuit, I suggest limiting the current to 100 uA. Connecting this 1.2-V reference voltage to a high-impedance buffer would be recommended if more current is needed.

    Regards,

    Ryan
