LTC2631 comes with options of an internal reference of 2.5V (-L) or 4.096V (-H). You can also use an external reference.
Can I power a -H part from 3.3V if I configure it for external reference and connect 3.3V to the reference pin?
The part I'm using is a -LZ, which means will default on power-up to internal reference.
But I will immediately change to internal.
Will it cause a problem when it briefly tries to drive its 4.096V internal reference while VCC=3.3V?
