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.
