LMC7211AIM5X/NOPB概述

    LMC7211 Tiny CMOS Comparator Technical Overview
    1. Product Introduction
    The LMC7211 is a miniature CMOS comparator designed to provide excellent performance in low-power and space-constrained applications. Available in a tiny SOT23-5 package, this comparator stands out due to its ultra-low supply current and rail-to-rail input/output capability. It is particularly suited for battery-powered electronics, including notebooks, PDAs, PCMCIA cards, mobile communications, and security/alarm systems.
    Key attributes of the LMC7211 include:
    - Tiny Footprint: SOT23-5 package with dimensions of 3.05 mm x 3.00 mm x 1.43 mm.
    - Wide Supply Voltage Range: Operates effectively between 2.7V and 15V.
    - Rail-to-Rail Inputs: Allows input signals to extend slightly beyond the power supply rails, enabling precise detection of analog signals.
    - Push-Pull Output: Capable of sourcing and sinking current efficiently.
    - Low Supply Current: Typical supply current is just 7 µA at 5V, maximizing battery life in portable devices.
    The LMC7211 offers two offset voltage grades: 5 mV and 15 mV, allowing flexibility in applications requiring high accuracy.
