(1) t
settle
is the settling time that the comparator output needs to have a stable level after VLD is switched from VLD ≠ 0 to a different VLD
value somewhere between 2 and 15. The overdrive is assumed to be >50 mV.
(2) The recommended operating voltage range is limited to 3.6 V.
(3) The current consumption of the SVS module is not included in the I
