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. The 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 1 dB. The LM3915's 3 dB\/step display is suited for signals with wide dynamic range, such as audio level, power, light intensity or vibration. Audio applications include average or peak level indicators, power meters and RF signal strength 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 interpretation of an analog display. The LM3915 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.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eFeatures:-\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e3 dB\/step, 30 dB Range \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDrives LEDs, LCDs, or Vacuum Fluorescents\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBar or Dot Display Mode Externally Selectable by User\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eExpandable to Displays of 90 dB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInternal Voltage Reference from 1.2V to 12V \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOperates with Single Supply of 3V to 25V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInputs Operate Down to Ground \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOutput Current Programmable from 1 mA to 30 mA \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eInput Withstands ±35V without Damage or \u003c\/span\u003e\u003cspan\u003eFalse\u003c\/span\u003e\u003cspan\u003e Outputs \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOutputs are Current Regulated, Open Collectors \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDirectly Drives TTL or CMOS \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe Internal 10-step Divider is Floating and can be Referenced to a Wide Range of Voltages The LM3915 is Rated for Operation from OOC to +700C.
