LMV331 Single / LMV393 Dual / LMV339 Quad
General Purpose, Low Voltage, Tiny Pack Comparators
General Description
The LMV393 and LMV339 are low voltage (2.7-5V) versions
of the dual and quad comparators, LM393/339, which are
specified at 5-30V. The LMV331 is the single version, which
is available in space saving 5-pin SC70 and 5-pin SOT23
packages. The 5-pin SC70 is approximately half the size of
the 5-pin SOT23.
The LMV393 is available in 8-pin SOIC and MSOP. The
LMV339 is available in 14-pin SOIC and TSSOP.
The LMV331/393/339 is the most cost-effective solution
where space, low voltage, low power and price are the pri-
mary specification in circuit design for portable consumer
products. They offer specifications that meet or exceed the
familiar LM393/339 at a fraction of the supply current.
The chips are built with National's advanced Submicron Sili-
con-Gate BiCMOS process. The LMV331/393/339 have bipo-
lar input and output stages for improved noise performance.
