The LMC7221AIM5 from Texas Instruments is a high-performance, low-power comparator that operates from a single +2.7V to +15V supply or a dual ±1.35V to ±8V supply. Its low power consumption makes it suitable for battery-powered applications.

• Product Features:
• Push-Pull Output: eliminates the need for an external pull-up resistor
• Rail-to-Rail Output Swing: even when operated from a low-voltage single supply
• Common-Mode Input Voltage Range: includes ground
• Low Power Consumption: 10µA of supply current
• Propagation Delay: 20us
• Small Package: 5-pin SOT-23 package
