It offers a simple way to display a logarithmic voltage level using one or more groups of ten LEDs with a minimum of fuss. The\u003cstrong\u003e LM3915\u003c\/strong\u003e monolithic IC senses analog voltage levels and drives ten LEDs, LCDs, or vacuum fluorescent displays with only a single resistor. Each LED connected to the \u003cstrong\u003eLM3915\u003c\/strong\u003e represents a 3 dB (decibel) change in the power level of the sensed signal.\u003c\/p\u003e\u003cp\u003eThe LEDs can appear in a bar graph or single ‘dotâ€?when in use so it is so commonly used with 5x5 Dot Matrix displays or the 10-segment LED bar display. The\u003cstrong\u003e LM3915\u003c\/strong\u003e IC has an operating voltage from 3V to 25V. The internal reference voltage for the IC can be set from 1.2V to 12V and the output current can be programmed to be from 2mA to 30mA according to the LED that is being driven. \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Description of LM3915 Dot\/Matrix Display Driver IC\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"LM3915 Dot\/Matrix Display Driver IC\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0300\/6424\/6919\/files\/Untitled-1_14af0531-1234-4834-9060-09764b56015b_600x600.jpg?v=1618571169\"\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures of LM3915 Dot\/Matrix Display Driver IC\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDrives LEDs, LCDs, or vacuum fluorescents\u003c\/li\u003e\n\u003cli\u003eBar or dot display mode externally selectable by the user\u003c\/li\u003e\n\u003cli\u003e3 dB\/step, 30 dB range\u003c\/li\u003e\n\u003cli\u003eOperates with a single supply of 3 V to 25 V\u003c\/li\u003e\n\u003cli\u003eInput withstands ±35V without damage\u003c\/li\u003e\n\u003cli\u003eOutputs are current regulated, open collectors\u003c\/li\u003e\n\u003cli\u003eOutput current programmable from 1 mA to 30 mA\u003c\/li\u003e\n\u003cli\u003eInternal voltage reference from 1.2V to 12V\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: 0 to 70 °C\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage Contents\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e1 x LM3915 Dot\/Matrix Display Driver IC\u003c\/p\u003e","brand":"mysite","offers":[{"title":"Default Title","offer_id":46018877128875,"sku":"CMP-QC0089","price":0.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/1205\/1115\/files\/LM3915-IC_e4553168-2d57-41c7-b998-cb278a7c649e.jpg?v=1767603317","url":"https:\/\/www.yuzxcn.com\/products\/lm3915-dot-matrix-display-driver-ic","provider":"Yuzx","version":"1.0","type":"link"}
