... The BA6144 is a driver IC for LED VU level meters in stereo equipment and other display applications. The IC displays the input level (range: *13dB to +17dB 5-point, bar-type LED display.The BA6144 includes a rectifier amplifier allowing direct AC input, and has constant-current outputs can directly drive the LEDs without variations in LED current due to supply voltage fluctuations ...

... If a resistor is connected in series with the LED, the LED 1 current will change if the supply voltage fluctuates. Note: If the power supply voltage exceeds 9V, insert a resistor in series with the LED current supply line, or connect a heat sink so that the maxi- mum power dissipation Pd Max. is not exceeded (see Fig. 4).
