a-2) Offset voltage fine adjustment (OCF)
The offset voltage is fine-tuned.
The offset adjustment voltage varies ratiometrically with respect to the supply voltage.
The ratio in the table below is benchmarked to a VOUT output of 4000mV (@VDD: 5V) as 100%
(ratio = (Offset voltage @VDD: 5V)/4000[mV]*100[%]).
