1.1.4 DIFFERENT V
REF
CONDITIONS
Some of the plots in Section 2.0, “Typical Performance
Curves”, have the conditions V
REF
=V
DD
/2 or
V
REF
=V
DD
. The equations and figures above are eas-
ily modified for these conditions. The ideal V
OUT
becomes:
EQUATION
The complete linear model is:
EQUATION
where the new V
IN
endpoints are:
EQUATION
The equations for extracting the specifications do not
change.
