The MAX918ESA from Maxim Integrated is a high-performance, low-power, single-supply comparator with a built-in reference. Designed for precision operation, this device is ideal for a wide range of applications, including battery-powered equipment, threshold detectors, and portable consumer electronics.

Key Features

• Integrated Precision Reference: The MAX918ESA includes a 1.232V ±1% reference voltage, which simplifies designs by eliminating the need for an external reference.
• Single-Supply Operation: This comparator operates from a single +2.5V to +11V supply or from dual supplies of ±1.25V to ±5.5V, providing flexibility for various circuit configurations.
• Low Power Consumption: With a quiescent current of just 150μA, the MAX918ESA is optimized for battery-powered and portable applications where power efficiency is critical.
• Fast Response Time: A fast propagation delay of typically 200ns ensures quick response times, making it suitable for high-speed signal processing tasks.
• High Input Impedance: The device features a high input impedance, which minimizes loading on the input source and preserves signal integrity.
• Internal Hysteresis: Built-in hysteresis improves noise immunity and prevents output oscillations, ensuring stable operation.
• Output Stage: The push-pull TTL/CMOS-compatible output can drive loads directly without the need for an external pull-up resistor.
