‡
t
settle
is the settling time that the comparator o/p needs to have a stable level after VLD is switched VLD ≠ 0 to a different VLD value somewhere
between 2 and 15. The overdrive is assumed to be > 50 mV.
NOTES: 1. The current consumption of the SVS module is not included in the I
CC
current consumption data.
2. The SVS is not active at power up.
