Los amplificadores operaticionales NanoPower MAX40018 (ART1206S)

Written by: Newton C. Braga
Category: Nuevos Componentes , Industria y Noticias

  Los amplificadores operacionales nanoPower Max40018 de Maxim presentan características de ultra bajo consumo de energía, del orden de 400 nA por canal, siendo ideales para aplicaciones alimentadas por batería. Con una alimentación simple de 1,7 a 5,5 V es ideal para aplicaciones con baterías de 1,6, 2,5 y 3,3 V. En este artículo enfocamos algunas de sus características y damos circuitos de aplicaciones del propio datasheet del producto componente.

   Los amplificadores operativos MAX40018 de Maxim se suministran en envoltorios WLP-8 y TDFN-8 con los pinos mostrados en la figura 1.
