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.
