The STK411-210E is a thick-film hybrid Integrated Circuit (IC) manufactured by Sanyo (now part of Panasonic)
The component comes packaged in a specialized footprint consisting of 22 functional pins. This layout optimizes trace routing while providing clear separation between high-current supply tracks and sensitive low-level audio input paths. Primary Configuration Functionality Description Pins 1 – 4 Input & Feedback Network Although the original circuit diagram is scarce, the
is a legend in the vintage repair community. While Sanyo stopped production decades ago, hobbyists still hunt for "New Old Stock" (NOS) modules to bring classic 90s stereo systems back to life.
Note: This pinout is based on standard configurations for the STK41x series. Before making any modifications to existing equipment, it is advisable to trace the circuit of the specific device to confirm pin functions.
This audio IC was a popular choice for OEM integration. It is confirmed to be used in the following models:
