Stacking LTC6655s for higher voltage references

I need to create an extremely low noise 15V reference. I am wondering if I can use the method described in Texas Instruments app note SBAA203 to make 15V using three LTC6655s: 

Will this work with the LTC6655? Will the noise and stability specs be maintained?

    Hi Justin,

    The connection of ref5010 will not fit the pins of LTC6655. And having the same pin doesn't necessarily mean that it will then work. 

    We have LT6657 which can be operated in shunt mode and can also achieve the same specs as its series mode.

    For more information about the shunt mode please see page 14 of the LT6657 datasheet.

    Regards,
