Maxim Integrated MAX924CSE-T Precision, Low-Power, Quad Voltage Comparators

The MAX924CSE-T from Maxim Integrated is a high-performance, precision voltage comparator designed for a wide range of applications requiring low power consumption and stable operation over time and temperature. This device is part of a family of low-power comparators that include on-chip voltage references, making them ideal for systems where precise voltage thresholds are critical.

With a typical supply current of just 4µA per comparator, the MAX924CSE-T is optimized for battery-powered and portable applications where power efficiency is paramount. The device operates from a single +2.5V to +11V supply or from dual ±1.25V to ±5.5V supplies, providing designers with flexibility in various circuit configurations.

The MAX924CSE-T features four independent voltage comparators in a single 16-pin SOIC package, making it an excellent choice for space-constrained designs. Each comparator is designed with an input voltage range that extends from the negative supply rail to within 1.3V of the positive supply rail, allowing for direct sensing near ground. Additionally, the comparators have a common-mode input voltage range that includes ground, even when powered from a single supply.

This device boasts a fast propagation delay of typically 20µs, ensuring quick response times in critical monitoring and control applications. The MAX924CSE-T also includes an internal 1.182V ±1% voltage reference, which can be used for setting precise threshold levels or as a precision voltage source for other components in the system.

With its low-power characteristics, integrated voltage reference, and compact form factor, the MAX924CSE-T is suitable for a variety of applications, including threshold detectors, window comparators, battery monitors, level translators, and more. The device's temperature range from -40°C to +85°C ensures reliable operation under varying environmental conditions, making it a versatile choice for industrial, automotive, and consumer electronics.
