The M51911 L/M51912L is a .semiconductor integrated circuit consisting of a circuit designed for LED level meters. It is capable of bar type display for 6 LEOs according to a input level. AC or DC signal can be inputed because of builtin superior half-wave rectification OP Amp. Output is a cascade connection of a pair of LEOs, so current for display is +half.
