BA6144 - LED level meter driver/ 5-point/ VU scale

Audio ICs LED level meter driver, 5-point, VU scale BA6144 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) on a 5-point, bar-type LED display.The BA6144 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 supply voltage fluctuations.

BA6144 Features

* 1) Rectifier amplifier allows either AC or DC input. 2) Wide display level range (

* 13 to +17), so signals with large dynamic range can be displayed. 3) Constant-current outputs for constant LED current when the power supply voltage fluctuates. 4) Built-in reference voltage means that power supp
