ic refers to IC chip
integrated circuit (integrated circuit) is a kind of miniature electronic device or component, using a certain process, the transistors, diodes, resistors, capacitors and inductors required in a circuit and wiring interconnect together, produced on a small or several small pieces of semiconductor chip or dielectric substrate, and then packaged in a tube shell, Becomes a micro structure with the desired circuit function; All components have been structurally formed as a whole, making electronic components a big step forward in terms of miniaturization, low power consumption and high reliability. It is represented in the circuit by the letter \"IC\".
