The LMV331IDCKR is a single general-purpose low-voltage comparator from Texas Instruments in a 5-pin SC-70 package measuring 2mm by 1.25mm. It runs from a supply between 2.7 volts and 5.5 volts drawing a maximum of 120µA, with an input offset voltage of 1.7 millivolts and an input bias current of 2.5 nanoamperes. The LMV331IDCKR has a propagation delay of 600 nanoseconds and an output current of 84 milliamperes. It is specified over -40°C to 125°C, is lead-free and RoHS compliant, and ships in tape-and-reel.

A comparator takes two analogue inputs and drives a logic-level output indicating which is larger, making it the standard building block for threshold detection where a full analogue-to-digital converter would be excessive. Devices in this class are used for battery and supply voltage monitoring, over-current and over-temperature trip circuits, zero-crossing and pulse detection, square-wave and oscillator generation, and squaring up slow sensor signals before a microcontroller input. The low supply current and SC-70 footprint on the LMV331IDCKR suit battery-powered and space-constrained boards. Buyers are embedded and portable product designers, sensor and instrumentation OEMs, and high-volume contract manufacturers.
