Waveplate
Configuration
To
get
a
quarter

oriented
at
a,
the
voltages
applied
to
the device
are
as
follows
:
V1
=

sin(2(x)
where
Vdc(0),
Vdc(90),
Vac(0),
and
Vac(90)
are the
four
characteristic
voltages
of
each
waveplate
.
Absolute
Maximum
Ratings
1-1255(F)a
Stresses
in
excess
of
the
absolute
maximum
ratings
can
cause permanent
damage
to
the device
.
These
are
abso-
lute
stress
ratings
only
.
Functional
operation
of
the
device
is
not
implied
at
these
or
any
other
conditions
in
excess
of
those
given
in
the
operational
sections
of
the
data
sheet
.
Exposure
to
absolute
maximum
ratings
for
extended
periods
can
adversely
affect
device
reliability
