LMV331/ LMV393

GENERAL PURPOSE LOW VOLTAGE COMPARATOR

Description

The LMV331/LMV393 series are low-voltage, (2.7V to 5.5V) single

and dual comparators, which are designed to effectively reduce cost

and space at low-voltage levels.

These devices offer specifications that meet or exceed the familiar

LM331/LM393 devices operating with a lower supply voltage and

consuming a far lower supply current.

The LMV331 is available in 5-Pin SOT353/SOT25 packages that

reduce space on PC boards and portable electronic devices. LMV393

is available in industry standard SOP-8 and MSOP-8 packages.
