IC de 8 pines usando Circuit-Tikz

Question

Parece que no puedo encontrar una manera sencilla de crear y mover circuitos integrados con CircuitTikz. Específicamente, quiero colocar un IC de amplificador operacional en algún lugar, digamos (5,5), y tener los pines correspondientes en relación con esas coordenadas, digamos el pin 1 en (5,5.5), el pin 2 en (5,6), etc.) para poder colocarlo en algún lugar y conectarlo relativamente rápido al resto del circuito. Pero no entiendo cómo hacer esto.

Aquí hay una imagen del amplificador operacional que estoy intentando implementar.

Answer 1

Aquí hay un DIP estándar de 8 pines deMi sitio web. Los anclajes incluyen p1 a p8. El tamaño se ajusta usando [pin spacing=...].
