LB1412

Ordering number: EN1218C Monolithic Digital IC LB1412 Level Meter Driver for 12 LEDs Functions and Features Package Dimensions unit : mm . Bar-shaped display of input level by means of 12 LEDs . High-order 5 dots with peak hold . Built-in oscillator for peak hold reset. Requires 1 pce. each . . . . . of external C, R. Uses either oscillator at the time of stereo operation. Capable of also resetting manually. Capable of constant-current driving low-order 7 dots (green LED). Constant-current value variable with an external resistor Lower current drain available by connecting green LEDs in series Built-in input amplifier Requires no other light-up level adjustment than adjustment for 0 dB.
