Segment 3
— This segment of the conversion cycle is
the same as Segment 1.
Segment 4
— Segment 4 is an up-going ramp cycle with
the unknown input voltage (V
X
) as the input to the integrator.
Figure 8 shows the equivalent configuration of the analog
section of the TC14433. The actual configuration of the
analog section is dependent upon the polarity of the input
voltage during the previous conversion cycle.
Segment 5
— This segment is a down-going ramp
period with the reference voltage as the input to the integra-
tor. Segment 5 of the conversion cycle has a time equal to
the number of counts stored in the offset storage latches
during Segment 2. As a result, the system zeros automati-
cally.
Segment 6
— This is an extension of Segment 5. The
time period for this portion is 4000 clock periods. The results
of the A/D conversion cycle are determined in this portion of
the conversion cycle.
