Pré-Amplificador Simples I (CIR579S)

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

Este circuito utiliza dos JFET que pueden ser el BF244 o BF245 y tiene una excelente ganancia con señales de pequeña intensidad. Su consumo es muy baja y se puede hacer con tensiones de 9 a 20 V. El consumo es de 8 mA con una impedancia de entrada de 1M ohm y una salida de 5 k ohmios. El nivel de la señal de salida es de unos pocos cientos de milivolts suficiente para excitar la mayoría de los amplificadores. En el montaje de los componentes debe mantenerse muy cerca uno del otro y los cables de señal deben estar blindados. Si se utiliza la fuente de alimentación, debe tener una excelente filtraje.
