Key Featrues
Beyond-the-Rails Inputs: The input voltage range extends 200mV beyond the supply rails, allowing for flexible signal monitoring even when the input signals are slightly outside the supply voltage range. This feature improves reliability in applications like sensing at ground or supply lines.
Internal 1.245V ±1.5% Reference: The MAX917/MAX918 include an accurate internal voltage reference, reducing the need for external components and simplifying circuit design. This is particularly beneficial in precision threshold detection and monitoring systems.
CMOS Push-Pull Output with ±8mA Drive Capability: The push-pull output configuration provides strong drive capability, enabling direct interfacing with other logic circuits or loads without additional buffering. This enhances performance in applications like mobile communications and telemetry systems.
Space-Saving SOT23 Package: The compact SOT23 package minimizes the footprint on the PCB, making these comparators suitable for space-constrained designs such as notebooks, PDAs, and medical instruments, without compromising performance.
Applications
Threshold Detection in Telemetry Systems: The MAX919 is perfect for threshold detection in telemetry and remote systems. Its Beyond-the-Rails™ input capability and nanopower operation allow it to function reliably in low-voltage environments, ensuring precise detection of signal thresholds in remote monitoring applications.
Ground or Supply Line Sensing: The MAX920 is well-suited for sensing signals at ground or supply lines in industrial and automotive systems. Its open-drain output and ultra-low power consumption make it an excellent choice for detecting voltage levels in harsh environments where power efficiency and reliability are critical.
Ultra-Low-Power Medical Instruments: The MAX918 is ideal for use in ultra-low-power medical instruments, such as wearable health monitors or implantable devices. Its internal hysteresis and crowbar-current-free switching ensure clean and reliable operation, while its nanopower design extends battery life in critical medical applications.
