Note 1:
VRL is the resistor ladder’s reference voltage. It is independent of VREF1:VREF0 selection.
2:
Gain selection of 2x requires voltage reference source to come from VREF pin and
requires VREF pin voltage ≤ VDD / 2.
3:
Requires G = 1, VREF1:VREF0 = 10 or ‘11’, and VRL ≤ VDD/2.
4:
These theoretical calculations do not take into account the Offset and Gain errors.
