MAX972CPA: Linear – Comparators

The MAX972CPA is a family of precision CMOS voltage comparators designed to enable high-speed, high-precision comparison of an input voltage with a reference voltage. With the ability to operate at ultra-low power, these comparators are ideal for automotive, IoT and battery-powered applications. The MAX972CPA family provides the industry’s highest precision and better than 1 microvolt resolution of any other comparators available. Each comparator offers one of the industry’s fastest and lowest power consumption ratings, including 8ns propagation delay and low-power mode.

Comparators are simple circuit elements found in a wide variety of applications such as level-sensing, over/under voltage protection, and switch contact debouncing. The MAX972CPA is no different. The MAX972CPA’s input range can be set from +/- 350mV to +/-6V. The comparator configuration includes a precision input stage, consisting of two matched PNP transistors and two NPN transistors, each with adjustable offset. The MAX972CPA is also designed to provide ultra-low power consumption with quiescent current of just100nA.

Now that we understand the general characteristics of the MAX972CPA family of comparators, let’s review the key features and processes of the MAX972CPA application that make it so versatile. As previously stated, the input range of the comparator can be programmed from +/-350mV to +/-6V. Additionally, the output can toggle between high and low with a single pin, providing extra flexibility and reducing the overall component count required. Furthermore, voltage regulators are integrated into the comparator, ensuring stable operation across a wide range of supply voltages. This allows for reliable operation in industrial, automotive and other harsh environments.

The greatest benefit of the MAX972CPA family is its precision and speed. This is achieved through its ultra-low voltage structure and CMOS process, allowing an unprecedented level of accuracy in comparison. The comparator is designed to achieve a maximum delay of 8ns and a comparative resolution of one microvolt or better. The low power consumption coupled with the high performance ensures that this device is capable of reliable and accurate operation over a wide supply voltage range.

In summary, the MAX972CPA family of precision CMOS voltage comparators offer amazing features and performance for applications where accuracy and low power consumption are critical design objectives. It is capable of providing ultra-precise comparison of two voltages with a resolution of one microvolt or better. The comparator also uses ultra-low power consumption, allowing it to be used in battery-powered and automotive applications. In addition, the comparator offers a wide range of adjustable input ranges and a single-pin output toggle, further simplifying integration into a system.
