M51911L - 6-STEP BAR TYPE LED LEVEL INDICATOR

Datasheet Summary

Description

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.

Features

  • Built-in superior half-wave rectification OP Amp. Cut off frequency 500kHz( typ. ) Input offset voltage.
  • 2mV( typ. ).
  • Output current is decided by internal circuit, so has few external parts. " "lo=13mA( typ. ).
  • Built-in reference voltage for threshold I.

MITSUBISHI LINEAR ICs M51911L M51912L 6·STEP BAR TYPE LED LEVEL INDICATOR DESCRIPTION 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. Display level of the M51911 L is logarithmical scale, 3 , 0,- 3 ,- 7 ,-12,-18dB. The M51912L is a companion. products to the M51911 L, display level is linear scale, 208mV step. FEATURES • Built-in superior half-wave rectification OP Amp.
