Diodes LMV393 User Manual

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.

Notes: 4. Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
