Overview
The LMV331IDCKR is a single general-purpose low-voltage comparator produced by Texas Instruments. It is part of the LMV33x family, which includes the LMV331, LMV393, and LMV339, designed as low-voltage versions of the industry-standard LM339 and LM393 comparators. The LMV331 operates from a supply voltage range of 2.7 V to 5.5 V, making it suitable for a wide range of applications, especially in low-power and space-constrained designs.
