the Datasheets states an operating voltage-range for VDD and VDDA of 1.71...3.6V.
The voltage-reference-module is equipped with a 1.75V regulator. It is also stated, that the regulator should be used to get the full performance.
I would like to opperate the device at low VCC, about 1.8V. Since the use of the chopper adds a 35ms delay (see topic "KL03 Voltage Reference Start-up Time") to get the refernce running, I would like to use the regulator w/o the chopper. I assume, that this implies the need for a little higher VDDA as there must be some headroom for the regulator.
Q: What is the minimum VDDA for the use of the regulator for VREF w/o enabling the chopper?
Thanks in advance
