Output Voltage Value
Two voltages are selected from all of the reference
voltages (V
0
-V
64
) by the upper 3-bit data (D
5
, D
4
and D
3
) of the 6-bit input data (D
5
, D
4
, D
3
, D
2
, D
1
and D
0
) taken by time sharing, and intermediate
value is determined by the lower 3-bit data (D
2
, D
1
and D
0
). The V
i
is a reference voltage (VH
i
or VL
i
)
that is determined by the polarity exchange input
(REV). Relation between input data and output
voltage values is shown below.
