Level Meter Driver for 12 LEDs
Functions and Features
. 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. D1 error: within ±3 dB of 20 dB
Supply voltage range : 10 to 16 V
