Abstract

AMPLIFICADOR OPERACIONAL. SE CARACTERIZA POR INCLUIR DOS ETAPAS DE ENTRADA DIFERENCIALES, CADA UNA DISEÑADAS PARA UNA GAMA MAXIMA DE VOLTAJE DE MODO COMUN, DE ENTRADA A UN LADO SOLAMENTE DE TIERRA. ESTAS DOS ETAPAS SE INTERCONECTAN CON DOS CAMINOS DE SALIDA DIFERENTES DE LA CORRIENTE DE SEÑALES, QUE PASAN CORRIENTE DE SEÑAL EN PROPORCION A LA POLARIDAD Y MAGNITUD DEL VOLTAJE DE LA SEÑAL DE ENTRADA. ESTAS CORRIENTES DE SALIDA DE SEÑAL SE COMBINAN, PARA DAR POR RESULTADO UNA SOLA HACIA UNA ETAPA DE SALIDA. LA GAMA DE MODO COMUN ES PRACTICAMENTE IGUAL A LOS VOLTAJES DE ALIMENTACION. CADA UNA DE LAS ETAPAS SEÑALADAS COMPRENDEN DOS TRANSISTORES DE ENTRADA DIFERENCIALES. DE APLICACION EN LA INDUSTRIA ELECTRONICA.
