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 Micro8, 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.
