Texas Instruments LMV331 Low Voltage Comparator, 1µs, SOT-23

The Texas Instruments LMV331IDBVR is a versatile single-channel, low-voltage analogue comparator designed for modern electronic applications. It operates from a supply voltage range of 2.7V to 5.5V, making it ideal for battery-powered and portable devices where power efficiency is crucial. The device consumes minimal power, supporting energy-saving circuit designs.

Its input common-mode voltage range includes ground, allowing for greater flexibility when sensing signals near the lower rail. A typical low output saturation voltage of 200mV helps minimise signal losses and power dissipation. The open-collector output provides maximum design flexibility, enabling easy interfacing with a wide range of logic levels and bus architectures.
