The MAX921EUA from Maxim Integrated is a high-performance, low-power comparator that operates from a single +2.5V to +11V supply or from dual ±1.25V to ±5.5V supplies. This versatile device is designed for applications requiring high-speed operation, low power consumption, and a wide operating voltage range.

Key Features

• High-Speed Operation: With a typical propagation delay of just 80ns, the MAX921EUA is ideal for fast systems that require quick response times.
• Low Power Consumption: The device's quiescent current is merely 4µA at +5V, making it suitable for battery-powered and portable applications where power efficiency is critical.
• Single-Supply Operation: The ability to operate from a single supply voltage simplifies power supply design and reduces system complexity and cost.
• Internal Hysteresis: Built-in hysteresis improves noise immunity and allows for clean output switching.
• Push-Pull TTL Outputs: The comparator features push-pull TTL outputs that can drive up to 8mA, eliminating the need for external pull-up resistors and ensuring compatibility with most TTL logic.
