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}
