Amplificador logarítmico (CIR19841S)

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

 

Este circuito es sugerido por Motorola y tiene características de respuesta logarítmica. Para señales de baja intensidad la ganancia es mayor y para señales más intensas la ganancia cae, proporcionando así un rango más amplio de intensidades de operación, sin distorsión ni saturación. La fuente de alimentación debe ser simétrica. El diodo D1 puede ser de uso general y el transistor admite equivalentes. El trimpot de 10 k ohms sirve para ajustar la corriente de compensación en el circuito para que la tensión de salida permanezca en cero en ausencia de una señal de entrada.
