LMV331 (ACTIVE) Single General Purpose Low-Voltage Comparator

 

Recommended alternative parts

  • TLV7021  -  Single 5uA, 260ns comparator
  • LM393  -  Dual differential comparator
  • LM311  -  Differential comparator with strobes
  • LM339  -  Quad differential comparator
  • TL331  -  Single wide voltage differential comparator

Description

The LMV393 and LMV339 devices are low-voltage (2.7 V to 5.5 V) versions of the dual and quad comparators, LM393 and LM339, which operate from 5 V to 30 V. The LMV331 is the single-comparator version.

The LMV331, LMV339, and LMV393 are the most cost-effective solutions for applications where low-voltage operation, low power, and space saving are the primary specifications in circuit design for portable consumer products. These devices offer specifications that meet or exceed the familiar LM339 and LM393 devices at a fraction of the supply current.
