LB1412
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

2-5 Reset pin (Pin 11)
When the reset pin is open, peak hold of D8 to D12 occurs. When the reset pin is connected to GND, reset occurs.
Connecting the reset pin to GND causes no peak hold.
2-6 C1, R1
The oscillation cycle of oscillator depends on the product of C1 and R1. The oscillation cycle at C1 = 2.2 µF, R1 =
1 MΩ is approximately 2 seconds. However, if an electrolytic capacitor is used for C1, the actual capacitance differs
from the marked value.
2-7 Reduction in number of parts
R3, R4, VR1 are substituted by one VR.
