Key Featrues
Ultra-Low Quiescent Current (4µA Max): The MAX931 series comparators feature an ultra-low quiescent current of 4µA maximum, even over extended temperature ranges. This significantly enhances power efficiency, making them ideal for battery-powered applications where minimizing power consumption is critical.
Wide Power Supply Range (Single +2.5V to +11V, Dual ±1.25V to ±5.5V): These comparators support a wide range of power supply voltages, both single and dual configurations. This flexibility allows them to be used in diverse applications, from low-voltage systems to higher-voltage industrial environments.
Internal 1.182V ±2% Bandgap Reference: The inclusion of a highly accurate internal voltage reference reduces the need for external components, simplifying circuit design and improving system reliability. This feature is particularly beneficial in precision threshold detection and window comparator applications.
Adjustable Hysteresis: The ability to adjust hysteresis helps in reducing false triggering due to noise or signal fluctuations. This improves the stability and reliability of the comparator in noisy environments, such as alarm circuits or sensor interfaces.
TTL/CMOS-Compatible Outputs: The TTL/CMOS-compatible outputs ensure seamless integration with a wide range of digital logic families. This feature enhances versatility, allowing the comparators to be used in both analog and digital systems without additional level-shifting circuitry.
