the incircuit programmable SLG46826 is very similar to the 46620 and 621. some very valuable options of the comparator have been lost in the process.
for example the 46620 comparator is able to sense near the supply line by using a gain of 0.25 for the input pin and a vdd/4 for the reference. this vdd/4 reference option has been deleted in the newer 46826 .
is there any chance this will be restored in newer devices ?

Hikoen@weijand.nl, If you need to controll VDD line just set IN+ source as VDD, IN+ gain e.g. x0.33 and choose IN- up to 2016mV ref. To controll some voltage which is close to supply line use IN+ with multiplier up to x0.25 and again IN- up to 2016mV ref. Do you have some special conditions which couldn't be covered by those combinations? Thanks.
