LED level meter driver, 5-point, VU scaleThe BA6137 is a driver IC for LED VU level meters in stereo equipment and other display applications. The IC displays the input level (range: \u000110dB to +6dB) on a 5-point, bar-type LED display.\u0001 1) Rectifier amplifier allows either AC or DC input.\n2) Constant-current outputs for constant LED current when the power supply voltage fluctuates.\n3) Current output is optimized for red LEDs, for low power dissipation.\n4) Built-in reference voltage means that power supply voltage fluctuations do;
