... LED/relay driving Optoisolator driving Control systems GENERAL DESCRIPTION The ADCMP341/ADCMP343 consist of two low power, high accuracy comparators with a 400 mV reference in an 8-lead SOT-23 package. Operating within a supply range of 1 5.5 V, the devices only draw 6.5 μA (typical), making them ideal for low voltage system monitoring and portable applications. ...
