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.
FApplications VU meters, signal meters, and other display devices.
FFeatures 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-c...
