The MAX9140EXK is a high-performance, single-supply comparator from Maxim Integrated that offers a perfect blend of speed, precision, and power consumption, making it an ideal choice for a variety of applications. This comparator operates from a single +2.5V to +5.5V supply and features a fast propagation delay of just 40ns while consuming low power.

Key Features:

• Fast Propagation Delay: With a propagation delay of only 40ns, the MAX9140EXK is designed for fast signal processing, which is critical in time-sensitive applications.
• Low Voltage Operation: The device can operate from a single +2.5V to +5.5V supply, accommodating a wide range of power sources and making it suitable for battery-powered devices.
• Low Power Consumption: It draws a quiescent current of just 85µA, which is advantageous for power-sensitive designs, helping to extend battery life and reduce thermal issues.
• No Output Phase Reversal: The comparator is designed to prevent output phase reversal with overdriven inputs, ensuring reliable operation even under extreme conditions.
• Internal Hysteresis: Internal hysteresis improves noise immunity and allows for clean output switching, making the MAX9140EXK robust against spurious signals.
• Push-Pull Output Stage: The push-pull output stage eliminates the need for an external pull-up resistor, simplifying design and reducing component count.
