Un pin cambia la pantalla de un gr\u00e1fico de barras a una pantalla de puntos en movimiento. La unidad de corriente LED es programable y regulable, eliminando la necesidad de resistencias limitadoras de corriente. Todo el sistema de visualizaci\u00f3n puede funcionar desde un solo suministro tan bajo como 3V o tan alto como 25V.<\/span><\/p>\n<p>El IC contiene una referencia de voltaje ajustable y un divisor de voltaje preciso de diez pasos. La entrada de alta impedancia en el b\u00fafer acepta se\u00f1ales a tierra y hasta 1,5 V de la oferta positiva. Adem\u00e1s, no necesita protecci\u00f3n contra entradas de \u00b1 35V. El b\u00fafer de entrada impulsa 10 comparadores individuales referenciados al divisor de precisi\u00f3n. La precisi\u00f3n es normalmente mejor que 1 dB.<br \/>\nLa pantalla de 3 dB \/ paso del LM3915 es adecuada para se\u00f1ales con amplio rango din\u00e1mico, como nivel de audio, potencia, intensidad de luz o vibraci\u00f3n. Las aplicaciones de audio incluyen promedio o pico indicadores de nivel, medidores de potencia y potencia de la se\u00f1al de RF metros. Reemplazo de medidores convencionales con una barra LED.<br \/>\nEl gr\u00e1fico da como resultado una pantalla de respuesta m\u00e1s r\u00e1pida y m\u00e1s resistente con alta visibilidad que conserva la facilidad de interpretaci\u00f3n de un pantalla anal\u00f3gica.<br \/>\nEl LM3915 es extremadamente f\u00e1cil de aplicar. Una escala completa de 1.2V<br \/>\nEl medidor requiere solo una resistencia adem\u00e1s de los diez LED.<br \/>\nUna resistencia m\u00e1s programa la escala completa desde<br \/>\n1.2V a 12V independientemente del voltaje de suministro. Brillo LED se controla f\u00e1cilmente con una sola olla.<\/p>\n<p><strong>Caracter\u00edsticas<\/strong><\/p>\n<ul>\n<li>Maneja hasta 10 LEDs individuales o de displays a LED, LCD, fluorescente o l\u00e1mparas incandescentes de baja corriente<\/li>\n<li>Expandible a displays de hasta 100 pasos<\/li>\n<li>Visualizaci\u00f3n en modo barra (todos los LEDs hacia atras encendidos) o modo punto (un solo LED encendido)<\/li>\n<li>Divisor intermo de 10 pasos en punto flotante que puede ser referenciado sobre un amplio rango de voltajes<\/li>\n<li>Referencia de voltaje interna de 1.2 V a 12 V<\/li>\n<li>Salidas reguladas en corriente y de colector abierto<\/li>\n<li>Las salidas pueden conectarse a TTL o CMOS<\/li>\n<li>Corriente de salida programable de 2 mA a 30 mA, lo que elimina la necesidad de resistores<\/li>\n<li>Las entradas soportan hasta \u00b135 V sin da\u00f1os o sin activar falsamente una salida<\/li>\n<li>Disipasi\u00f3n max. del encapsulado: 1365 mW<\/li>\n<li>Voltaje de alimentaci\u00f3n: 3 V a 25 V<\/li>\n<li>Encapsulado: DIP 18 pines<\/li>\n<\/ul>\n<p>El divisor interno de 10 pasos es flotante y puede\u00a0 referenciado a una amplia gama de voltajes<br \/>\nEl LM3915 est\u00e1 clasificado para funcionar de 0\u02daC a + 70\u02daC. Los LM3915N-1 est\u00e1 disponible en un paquete DIP moldeado de 18 derivaciones.<\/p>\n<p><strong>DESCRIPCION FUNCIONAL<\/strong><br \/>\nSe incluye el diagrama de bloques simplificado del LM3915 para dar una idea general del funcionamiento del circuito. Una gran entrada<br \/>\nEl b\u00fafer de impedancia opera con se\u00f1ales de tierra a 12V y est\u00e1 protegido contra reversa y sobretensi\u00f3n<br \/>\nse\u00f1ales. Luego, la se\u00f1al se aplica a una serie de 10 comparadores; cada uno de los cuales est\u00e1 sesgado a un diferente<br \/>\nnivel de comparaci\u00f3n por la cadena de resistencias.<br \/>\nEn el ejemplo ilustrado, la cadena de resistencias est\u00e1 conectada a la tensi\u00f3n de referencia interna de 1,25 V. En este caso, para<br \/>\ncada 3 dB que aumenta la se\u00f1al de entrada, un comparador encender\u00e1 otro LED indicador. Esta resistencia<br \/>\nEl divisor se puede conectar entre 2 voltajes cualesquiera, siempre que est\u00e9n al menos 1,5 V por debajo de V<br \/>\n+ y no menor que V-.<\/p>\n<p>Voltaje\u00a0necesario\u00a0en\u00a0la\u00a0entrada\u00a0para encender cada led<\/p>\n<table border=\"2\" width=\"306\" cellspacing=\"2\" cellpadding=\"3\">\n<tbody>\n<tr>\n<th align=\"center\" width=\"100\">LED<\/th>\n<th align=\"center\" width=\"100\">LM3914<\/th>\n<th align=\"center\" width=\"100\">LM3915<\/th>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">1<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">125mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">60mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">2<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">250mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">80mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">3<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">375mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">110mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">4<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">500mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">160mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">5<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">625mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">220mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">6<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">750mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">320mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">7<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">875mV<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">440mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">8<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">1V<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">630mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">9<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">1.125V<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">890mV<\/td>\n<\/tr>\n<tr>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">10<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">1.25V<\/td>\n<td class=\"row\" align=\"center\" valign=\"middle\" width=\"96\">1.25V<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>PinOut<\/strong><\/p>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/LM3915-display-Driver-Pinout.png\"><img loading=\"lazy\" class=\"alignnone wp-image-5819\" src=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/LM3915-display-Driver-Pinout.png\" alt=\"\" width=\"387\" height=\"349\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/LM3915-display-Driver-Pinout.png 626w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/LM3915-display-Driver-Pinout-300x270.png 300w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/LM3915-display-Driver-Pinout-600x541.png 600w\" sizes=\"(max-width: 387px) 100vw, 387px\" \/><\/a><\/p>\n<p><strong>Diagrama de bloques<\/strong><\/p>\n<p><a href=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques.png\"><img loading=\"lazy\" class=\"alignnone wp-image-5806\" src=\"http:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-637x1024.png\" alt=\"\" width=\"457\" height=\"735\" srcset=\"https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-637x1024.png 637w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-187x300.png 187w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-768x1235.png 768w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-600x965.png 600w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-820x1318.png 820w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques-1320x2122.png 1320w, https:\/\/rogerbit.com\/wprb\/wp-content\/uploads\/2020\/08\/bloques.png 1534w\" sizes=\"(max-width: 457px) 100vw, 457px\" \/><\/a><\/p>\n<h3><strong>Conexi\u00f3n en cascada.<\/strong><\/h3>\n<p style=\"font-weight: 400;\">Podemos conectar ambos circuitos integrados en cascada (dos LM3915).
