BL8509
Function description:
Delay
Comparator
High precision low temperature co-efficiency reference voltage is applied to the
negative input of a comparator. Input voltage, divided by resistor array of Ra and Rb, is
applied to the positive input of the comparator. Output of the comparator passes a delay
circuit and a series of buffer to drive the output CMOS pair.
VDET =VREF*(1+Ra/Rb)
