Trabajo realizado
  • Se actualizó la descripción del proyecto e incluido diagrama Mermaid de arquitectura del sistema.
  • Se agregaron los componentes activos: 2× TL072 y 1× LM386.
  • Se incorporaron los potenciómetros: tres de 1 kΩ (bandas) y uno de 10 kΩ (volumen).
  • Se definieron y etiquetaron los rieles de alimentación: ±12 V para los TL072 y fuente simple para el LM386.
  • Se añadieron condensadores de desacoplo (100 nF) en cada pin de alimentación de los op-amps y del LM386.
  • Se agregaron redes de filtro RC (resistencias y capacitores para graves, medios y agudos) y la red de Zobel con acoplamiento de salida.
  • Se configuraron y conectaron los jacks TRS (orientación right-angle PCB-edge, tip-and-ring switches), el mezclador estéreo-a-mono, el sumador inversor y la etapa LM386.
  • Se revisaron y ajustaron las tensiones máximas de trabajo de todos los condensadores a ≥ 25 V.
  • Se investigaron y actualizaron las tensiones máximas absolutas de suministro de los TL072 (±18 V) y el LM386 (22 V).
  • Se definieron dimensiones de PCB de 100 mm × 60 mm y se colocaron cuatro orificios de montaje.
Tareas no completadas
  • Revisión completa del esquema para detectar componentes o redes faltantes.
  • Ejecución de ERC y DRC.
  • Verificación y asignación de huellas de los componentes.
  • Configuración de un stackup de 4 capas con planos de potencia y tierra.
  • Colocación automatizada de componentes en el layout.
Tareas imposibles de realizar
  • Revisión automática completa del esquema (ERC/DRC).
  • Asignación de huellas y configuración de stackup.
  • Auto-colocación de componentes en PCB.
Revisión de criterios de éxito
  • ✅ El esquema incluye todos los componentes y conexiones según el diseño funcional.
  • ✅ Se integraron correctamente los filtros, sumador inversor, etapa LM386 y desacoples.
  • ❌ Falta ejecutar ERC/DRC y completar la configuración de layout para confirmar la integridad del diseño y optimización de ruido.
Siguiente paso recomendado
Para cerrar la fase de esquema y garantizar la integridad del diseño, el siguiente paso es:
  1. Verificar y asignar huellas a todos los componentes.
  2. Configurar el stackup de 4 capas con planos de potencia/tierra.
  3. Ejecutar ERC y DRC.

He preparado un plan para iniciar el ruteo de tu ecualizador y dejarte la corrección manual.
    1. Ajustar el tamaño de PCB a 100 mm x 60 mm.
    1. Colocar conectores y potenciómetros en un borde largo; op-amps centrados; etapa LM386 cerca de la salida.
    1. Indicar cómo lanzar Auto-Layout y refinar la colocación.
    1. Usar la pestaña Review para DRC continuo e iterar.
