LM3916  
Dot/Bar Display Driver  
The LM3916 is very versatile. The outputs can drive LCDs,  
vacuum fluorescents and incandescent bulbs as well as  
LEDs of any color. Multiple devices can be cascaded for a  
dot or bar mode display for increased range and/or resolu-  
tion. Useful in other applications are the linear LM3914 and  
the logarithmic LM3915.  
General Description  
The LM3916 is a monolithic integrated circuit that senses  
analog voltage levels and drives ten LEDs, LCDs or vacuum  
fluorescent displays, providing an electronic version of the  
popular VU meter. One pin changes the display from a bar  
graph to a moving dot display. LED current drive is regulated  
and programmable, eliminating the need for current limiting  
resistors. The whole display system can operate from a  
single supply as low as 3V or as high as 25V.  
Features  
n Fast responding electronic VU meter  
n Drivers LEDs, LCDs, or vacuum fluorescents  
n Bar or dot display mode externally selectable by user  
n Expandable to displays of 70 dB  
The IC contains an adjustable voltage reference and an ac-  
curate ten-step voltage divider. The high-impedance input  
buffer accepts signals down to ground and up to within 1.5V  
of the positive supply. Further, it needs no protection against  
n Internal voltage reference from 1.2V to 12V  
n Operates with single supply of 3V to 25V  
n Inputs operate down to ground  
±
inputs of 35V. The input buffer drives 10 individual com-  
parators referenced to the precision divider. Accuracy is typi-  
cally better than 0.2 dB.  
n Output current programmable from 1 mA to 30 mA  
Audio applications include average or peak level indicators,  
and power meters. Replacing conventional meters with an  
LED bar graph results in a faster responding, more rugged  
display with high visibility that retains the ease of interpreta-  
tion of an analog display.  
±
n Input withstands 35V without damage or false outputs  
n Outputs are current regulated, open collectors  
n Directly drives TTL or CMOS  
n The internal 10-step divider is floating and can be  
referenced to a wide range of voltages  
The LM3916 is extremely easy to apply. A 1.2V full-scale  
meter requires only one resistor in addition to the ten LEDs.  
One more resistor programs the full-scale anywhere from  
1.2V to 12V independent of supply voltage. LED brightness  
is easily controlled with a single pot.  
The LM3916 is rated for operation from 0˚C to +70˚C. The  
LM3916N-1 is available in an 18-lead molded DIP package.
