B1423N - 5-Dot Red/Green LED Level Meter

Download the B1423N datasheet PDF. This datasheet also covers the B1403N variant, as both devices belong to the same 5-dot red/green led level meter family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • and Functions.
  • Capable of generating a bar-display for input voltage with 5 LEDs.
  • Operates from either AC or DC input voltage because of on-chip rectifier amplifier.
  • Lighting levels remain stable to line regulation because of on-chip voltage reference.
  • LEDs are driven by a constant current ; stable to line regulation.
  • Power supply voltage range is wide (3.5 to 16V), for a wide range of.
