LMV331, LMV393, LMV339
Single, Dual, Quad General
Purpose, Low Voltage
Comparators
The LMV331 is a CMOS single channel, general purpose, low
voltage comparator. The LMV393 and LMV339 are dual and quad
channel versions, respectively. The LMV331/393/339 are specified
for 2.7 V to 5 V performance, have excellent input common−mode
range, low quiescent current, and are available in several space saving
packages.
The LMV331 is available in a 5−pin SC−70, a TSOP−5, and a
ULLGA8 package. The LMV393 is available in a 8−pin Micro8t,
SOIC−8, and a UDFN8 package, and the LMV339 is available in a
SOIC−14 and a TSSOP−14 package.
The LMV331/393/339 are cost effective solutions for applications
where space saving, low voltage operation, and low power are the
primary specifications in circuit design for portable applications.
