634 Audio ICs LED level meter driver, 5-point, VU scale BA6144

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. Applications include VU meters, signal meters, and other display devices.
