Overview
The LMV331ICT, produced by STMicroelectronics, is a single-channel, general-purpose, low-voltage comparator. It is part of the LMV3xx series, which includes single, dual, and quad versions of the industry-standard LM339 and LM393 comparators. These devices are designed to operate with a supply voltage ranging from 2.7 to 5 V and exhibit lower current consumption compared to their predecessors. The LMV331ICT is ideal for low-voltage applications and is available in space-saving packages such as the SC70-5 and SOT23-5, making it suitable for applications where space is a constraint.
