Figure 7. Response to 100MHz Sine Wave Photo
By combining two quad analog comparators with an
octal 8-bit D/A converter (the MX7228), several alarm
and limit-defect functions can be performed simultane-
ously without external adjustments
The MX7228’s internal latches allow the system
processor to set the limit points for each comparator
independently and update them at any time. Set the
upper and lower thresholds for a single transducer by
pairing the D/A converter and comparator sections.
