2: The V
OS
spec limits include 1/f noise effects.
3: This is the input offset drift without V
OS
re-calibration; toggle EN/CAL to minimize this effect.
4: These specs apply to both the V
IP
, V
IM
input pair (use V
CM
) and to the V
REF
, V
FG
input pair (V
REF
takes V
CM
’s place).
5: This spec applies to the V
IP
, V
IM
, V
REF
and V
FG
pins individually.
6: Figure 2-11 and Figure 2-19 show the V
IVR
and V
DMR
variation over temperature.
