Activity: Temperature Control using Window Comparator


The objective of this lab activity is to use two high speed voltage comparators as a Window-Comparator and program the TMP01 Low Power Programmable Temperature Controller using this approach.

A Window-Comparator is a circuit configuration, usually consisting of a pair of voltage comparators (inverting and non-inverting), in which the output indicates whether an input signal is within the voltage range bounded by two different thresholds. One which triggers an op-amp comparator on detection of some upper voltage threshold, VREF(HIGH) and one which triggers an op-amp comparator on detection of a lower voltage threshold level, VREF(LOW). The voltage levels between these two upper and lower reference voltages is called the “window”.
