Key Featrues
Fast 40ns Propagation Delay: The MAX9140/MAX9141/MAX9142/MAX9144 comparators feature a rapid 40ns propagation delay with a 10mV overdrive, ensuring quick response times in high-speed applications. This makes them ideal for time-critical systems like sampling circuits and zero-crossing detectors, where speed is essential for accurate performance.
Low Power Consumption: With a supply current of only 150µA per comparator at 3V, these devices are highly efficient, making them suitable for battery-powered systems and other low-power applications. This low power consumption extends battery life and reduces energy costs in portable and energy-sensitive designs.
Rail-to-Rail Input Voltage Range: The comparators support rail-to-rail input voltage ranges, allowing them to handle signals close to the power supply rails. This feature enhances versatility in 3V/5V systems, enabling accurate signal detection and processing across a wide range of input voltages.
Internal Hysteresis for Clean Switching: The built-in hysteresis of 1.5mV ensures clean and stable switching, reducing the likelihood of false triggering in noisy environments. This is particularly beneficial in threshold detectors and discriminators, where signal integrity is critical.
CMOS/TTL-Compatible Outputs: The comparators feature CMOS/TTL-compatible outputs, making them compatible with a wide range of digital logic systems. This flexibility simplifies integration into mixed-signal designs, such as line receivers and sampling circuits, where interfacing with both analog and digital components is required.
