Working Principle

The MAX966ESA is a low-voltage, output-signal comparator. It compares the input levels of two signals and outputs the result based on a logic condition. The output will be active (high) when the input voltage of one signal is greater than the input voltage of the other. When the two inputs are at the same voltage, the output will be inactive (low).

The MAX966ESA features two differential inputs, A and B. By comparing the input voltages of these two inputs, it is possible to determine the difference in voltage. If the voltage of A is higher than that of B, the output of the comparator will be active (high). Likewise, if the voltage of A is lower than that of B, the output of the comparator will be inactive (low).

The MAX966ESA also features a low-input offset voltage of typically 0.5 mV. This is the difference in voltage between the comparator\'s A and B input pins at zero differential input. This low-input offset voltage is ideal for precision threshold detection or DC-offset calibration applications.

The MAX966ESA has a maximum propagation delay time (tPD) of 500 ns. This is the time it takes for the comparator to process the inputs and output its result. This makes the MAX966ESA ideal for applications that require a fast response time.

Conclusion

The MAX966ESA is an ultra-precise, single-output comparator from Maxim Integrated. It has a wide supply voltage range of ±2.25 V to ±18 V, with a maximum propagation delay time (tPD) of 500 ns. It features two differential inputs and low-input offset voltage of typically 0.5 mV. With its low-voltage and small size, it is ideal for a variety of applications such as power-supply sequencing and monitoring, precision DC-offset calibration, digital-to-analog converters, and many more.
