Switchpoints
Switchpoints in the ATS673 and ATS674 are established dynami-
cally as a percentage of the amplitude of the signal, V
PROC
, after
normalization with AGC. Two DACs track the peaks of V
PROC
(see the Update subsection).
The switching thresholds are established at fixed percentages
of the values held in the two DACs. The value of the thresholds
has been carefully selected, where the signal is steepest and least
affected by air gap variation, thus providing the most accurate
and consistent switching.
The low hysteresis, 10%, provides high performance over vari-
ous air gaps while maintaining immunity to false switching on
noise, vibration, backlash, or other transient events.
Figure 8 graphically demonstrates the establishment of the
switching threshold levels. Because the thresholds are estab-
lished dynamically as a percentage of the peak-to-peak signal,
the effect of a baseline shift is minimized.
