Oscilador de potencia para transductor piezoeléctrico (CIR19842S)

Written by: Newton C. Braga
Category: Banco de circuitos

 

Este circuito es sugerido por National Semiconductor y está basado en el LM3900, un amplificador operacional de transconductancia cuádruple. La frecuencia de funcionamiento del circuito es la de la resonancia del transductor y se consigue una excelente potencia de audio con este tipo de elemento. La alimentación de 15 V proviene de una fuente no simétrica. Los otros operacionales del circuito integrado LM3900 se pueden utilizar para otras aplicaciones o para generar señales para otros transductores.
