• LED LCD BAR Driver Control VU-meter LM3916 DIP-18

Informatie (ENG):

The LM3916 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing an

• Fast Responding Electronic VU Meter
• Drivers LEDs, LCDs, or Vacuum Fluorescents
• Bar or Dot Display Mode Externally Selectable
• Expandable to Displays of 70 dB
• Internal Voltage Reference from 1.2V to 12V
• Operates with Single Supply of 3V to 25V
• Inputs Operate Down to Ground
• Output Current Programmable from 1 mA to 30 The IC contains an adjustable voltage reference and
• Input Withstands ±35V without Damage or False Outputs
• Outputs are Current Regulated, Open Collectors
• Directly Drives TTL or CMOS
• The Internal 10-step Divider is Floating and Audio applications include average or peak level indicators, and power meters. Replacing conventional can be Referenced to a Wide Range of meters with an LED bar graph results in a faster Voltages

electronic version of the popular VU meter. One pin by User 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. The high- mA impedance input buffer accepts signals down to ground and up to within 1.5V of the positive supply. Further, it needs no protection against inputs of ±35V. The input buffer drives 10 individual comparators referenced to the precision divider. Accuracy is typically better than 0.2 dB. responding, more rugged display with high visibility The LM3916 is Rated for Operation from 0°C to that retains the ease of interpretation of an analog +70°C. The LM3916N-1 is Available in an 18- display. lead PDIP Package. 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 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 resolution. Useful in other application are the linear LM3914 and the logarithmic LM3915.
