MAX924MJE概述

    Product Introduction: MAX921–MAX924 Ultra Low-Power Comparators
    The MAX921–MAX924 series from Maxim Integrated Products offers advanced low-power, single/dual-supply comparators designed for a variety of applications requiring minimal power consumption. This product line includes both single, dual, and quad configurations, making it suitable for space-constrained designs while ensuring high reliability and efficiency. The comparators find applications in battery-powered systems, threshold detectors, window comparators, and oscillator circuits. Their ultra-low power consumption and versatile supply options make them ideal for environments where power efficiency is paramount.
    Technical Parameters
    | Parameter | Value |

    | Quiescent Current | ≤4µA (MAX921/MAX922) |
    | Supply Voltage | +2.5V to +11V (single) |
    ±1.25V to ±5.5V (dual) |
    | Reference Voltage | 1.182V ±1% |
    | Propagation Delay | 3µs (with 100mV overdrive) |
    | Continuous Source Current| Up to 40mA |
    | Input Voltage Range | V- to (V+ – 1.3V) |
    Additional specifications include:
    - Adjustable hysteresis via the HYST pin.
    - TTL/CMOS-compatible outputs that can sink and source current.
    - Extended operating temperature ranges:
    - Commercial (-40°C to +85°C),
    - Industrial (-55°C to +125°C).
    Product Features and Advantages
    Unique Features:
    1. Minimal Power Consumption: The MAX921–MAX924 consume less than 4µA of quiescent current across the entire temperature range, reducing power dissipation and extending battery life in portable electronics.
    2. Precision Reference: An integrated 1.182V ±1% voltage reference ensures stable performance under varying environmental conditions.
    3. Programmable Hysteresis: Easy adjustment of hysteresis without feedback circuits simplifies design complexity.
    4. Immunity to Parasitic Feedback: The output stage minimizes switching glitches, enhancing reliability and reducing noise.
    Market Competitiveness:
    The MAX921–MAX924 stands out in terms of its low power consumption, compact footprint, and adaptability to multiple supply configurations. Its ability to support both single and dual supply modes further enhances its applicability in diverse electronic systems.
    Application Cases and Usage Suggestions
    Applications:
    - Battery-Powered Systems: Ideal for IoT devices, wearables, and remote sensors where prolonged battery life is critical.
    - Threshold Detectors: Utilize the comparator’s precise switching characteristics to monitor thresholds in sensor-based systems.
    - Window Comparators: The dual/multi-channel options enable accurate detection within a specific voltage range.
    Usage Recommendations:
    - For high-precision applications, calibrate the hysteresis level to avoid false triggering due to noise.
    - Ensure that the input signals remain within the specified common-mode range to maximize accuracy and prevent degradation of performance.
    - Implement decoupling capacitors near the power supply pins to mitigate transient effects and stabilize the circuit.
    Compatibility and Support
    The MAX921–MAX924 series supports integration with a wide range of electronic components, including microcontrollers, digital logic, and analog interfaces. Maxim Integrated provides comprehensive documentation, application notes, and technical support through their official channels (Maxim Direct or www.maxim-ic.com).
