DESCRIPTION/ORDERING INFORMATION
The LMV393-Q1 device is a low-voltage (2.7 V to 5.5 V) version of the dual and quad comparators, LM393 and
LM339, which operate from 5 V to 30 V. The LMV331-Q1 is the single-comparator version.
The LMV331-Q1 and LMV393-Q1 are the most cost-effective solutions for applications where low-voltage
operation, low power, space saving, and price are the primary specifications in circuit design for portable
consumer products. These devices offer specifications that meet or exceed the familiar LM339 and LM393
devices at a fraction of the supply current.
