Comparator Output
By monitoring the comparator output during the fixed
signal integrate time, the input signal polarity can be deter-
mined by the microprocessor controlling the conversion.
The comparator output is HIGH for positive signals and LOW
for negative signals during the signal-integrate phase (see
timing diagram).
During the reference deintegrate phase, the comparator
output will make a HIGH-to-LOW transition as the integrator
output ramp crosses zero. The transition is used to signal the
processor that the conversion is complete.
The internal comparator delay is 2
μ
sec, typically. Figure
5 shows the comparator output for large positive and nega-
tive signal inputs. For signal inputs at or near zero volts,
however, the integrator swing is very small. If common-
mode noise is present, the comparator can switch several
times during the beginning of the signal-integrate period. To
ensure that the polarity reading is correct, the comparator
output should be read and stored at the end of the signal
integrate phase.
The comparator output is undefined during the Auto-
Zero Phase and is used to time the Integrator Output Zero
phase. (See Integrator Output Zero Phase of System Timing
section).
