8-Channel Comparator with Programmable Thresholds

The S3DACMPTD8C90 combines eight low-power programmable threshold comparators where the programmable thresholds are implement using eight digital-to-analog converters (DACs) which drive the comparator inverting inputs so the that individual trip thresholds can be digitally set. Each programmable threshold is also available externally by means of interchanging them with the comparator inputs.

Each comparator goes high when its analog input exceeds its digitally set threshold.

The DAC is implemented using a current steering architecture which drives current into a resistive load.
