/GAIN. If V
REF
is
sourced externally, the analog input range should not exceed 80% of V
FS+
or V

; that is, V
ID
= 0.8 V
FS-
to 0.8 V
FS+
. If V
REF
is sourced
internally, the given V
ID
ranges apply. MIN values are calculated based on a V
REF
of 1.125V. TYP values are calculated based on a
V
REF
of 1.16 V.

There is no capacitance required on VREF. However, a capacitance of 100nF is recommended to reduce any reference voltage noise.
