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.
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-current outputs for constant LED current
when the power supply voltage fluctuates.
4) Built-in reference voltage means that power supply
voltage fluctuations do not effect the display.
5) Wide operating power supply voltage range (5.5V to
16V) for a wide range of applications.
6) Low PCB space requirements. Comes in a compact
9-pin SIP package and requires few external compo-
nents.
FAbsolute maximum ratings (Ta = 25_C)
