Analog Comparators (Maximum Propogation Delay: 1.7µs)
An analog comparator is an electronic circuit that compares which of the two input signals is greater and switches the output signal. It is used in all situations, such as comparing which of two flowing currents or voltages is greater than a reference, and comparing which value is higher in other signals. An analog signal is used for input and a digital signal is used for output. TTL level or CMOS level, open collector, push-pull, etc. are the main types. One of the features is that no negative feedback is applied. The operation can be performed at high speed, and the maximum propagation delay can be selected from those with 0.085 ns. It is also characterized by high sensitivity, but malfunctions such as chattering are likely to occur, and it is effective to provide a hysteresis function as a prevention.
