Описание

The LM3916N-1 is a Dot/Bar Display Driver which senses analogue 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. This IC contains an adjustable voltage reference and an accurate 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 inputs of ±35V. The input buffer drives 10 individual comparators referenced to the precision divider. Accuracy is typically better than 0.2dB. A 1.2V full-scale meter requires only one resistor in addition to the ten LED's and LED brightness is easily controlled with a single pot.

• Fast responding electronic VU meter
• Bar or dot display mode externally selectable by user
• Inputs operate down to ground
• Outputs are current regulated, open collectors
