Description

The BA6137 is a driver IC for LED VU level meters in stereo equipment and other display applications. The IC displays
the input level (range: 10dB to +6dB) on a 5-point, bar-type LED display.

The BA6137 includes a rectifier amplifier allowing direct AC input, and has constant-current outputs, so it can directly
drive the LEDs without variations in LED current due to power supply voltage fluctuations.
