Overview
The LMV331SN3T1G, produced by onsemi, is a CMOS single-channel, general-purpose, low-voltage comparator. It is part of the LMV331 series, which includes dual and quad channel versions (LMV393 and LMV339, respectively). This comparator is designed for low-voltage applications, operating within a supply voltage range of 2.7 V to 5 V. It is known for its excellent input common-mode range, low quiescent current, and availability in several space-saving packages, including the 5-pin SC-70 package for the LMV331SN3T1G.
