LM4558
by Gcore(扬州国芯)For audio gain stages and general analog signal conditioning, the LM4558 provides a dual operational-amplifier building block. Its amplifier channels suit gain and active-filter circuits, while the supplied SOP-8 package supports surface-mount assembly. This Gcore(扬州国芯) part entered ProtoFlow through a real import; the resulting conversion was checked in the editor. Available free for KiCad, the files include an eight-pin schematic symbol, the eight-pad SOP-8_L4.9-W3.9-P1.27-LS6.0-BL footprint, and a 3D model. The package assets let the analog circuit and its physical placement use the same component record. The LM4558 can be opened directly in ProtoFlow.
