1.7V, 0.9μA, Comparators with Built-in Reference


  • Very low power - 0.9µA of supply current
  • Small footprint 1.11mm x 0.76mm
  • Initial accuracy of 1%
  • Supply voltage range from 1.7V to 5.5V

The MAX40000/MAX40001 are tiny, single comparators with built-in voltage references that are ideal for a wide variety of portable electronics applications. The devices offer a supply voltage range from 1.7V to 5.5V and consume only 0.9µA of supply current. They also feature internal filtering to provide high RF immunity, important in many portable applications.
