Stk411-210e Datasheet !!link!! File
Operates on a dual (positive/negative) power supply.
The is a high-performance, two-channel thick-film hybrid audio power amplifier integrated circuit (IC) originally engineered by Sanyo Electric Co., Ltd. . Renowned for its presence in high-fidelity (Hi-Fi) home audio systems, shelf stereos, and specialized power applications, this classic module utilizes Sanyo’s proprietary Insulated Metal Substrate Technology (IMST) to offer robust thermal performance, minimal external component counts, and superb sound replication. Audio engineers and DIY hobbyists routinely consult the STK411-210E Datasheet on ALLDATASHEET to troubleshoot legacy stereo equipment or build highly stable, split-power amplification circuits. Comprehensive Technical Specifications
Allows for easy power management and reduces idle current when the amplifier is not in use.
Features an integrated muting pin to suppress turn-on and turn-off thumps or clicks, protecting connected loudspeakers.
: Providing medium-power amplification with low distortion ( Compact Audio Units Stk411-210e Datasheet
Yes, some later production runs of the STK411-210E are labeled as and RoHS compliant (Restriction of Hazardous Substances).
The STK411-210E is a reliable and efficient power amplifier IC, designed for high-quality audio applications. Its high power output, low distortion, and wide operating voltage range make it an excellent choice for a variety of audio equipment designs.
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.
directly to the output, which will instantly destroy your speakers. 6. Conclusion Operates on a dual (positive/negative) power supply
Before replacing the IC, check the external electrolytic capacitors and resistors, as these are often the cause of failure. 6. Conclusion
The STK411-210E remains an important component in the history of Japanese consumer audio, a prime example of Sanyo's hybrid module technology. While many modern amplifier designs have moved to discrete Class D topologies, the STK411-210E and its STK-series siblings are still found in thousands of legacy devices, from old Sony mini-systems to JVC stereo towers. For the modern hobbyist, the STK411-210E is repairable with a correct replacement, or it can be a candidate for a complete amplifier transplant. Whether you are restoring vintage equipment or simply need a specification sheet, this guide aims to provide the definitive resource for understanding this unique chip.
Would greatly appreciate any experience or documentation you can share. I’m considering using this in a retro audio restoration project.
In the late 1980s, economic shifts made traditional high-end audio equipment extremely expensive to produce. Sanyo’s STK modules "hit the jackpot" by providing a "cookie-cutter" solution that allowed brands like Panasonic (Technics) to rapidly assemble powerful home theater and rack systems. STK411-210E specifically became a workhorse for: Home Theater Systems Renowned for its presence in high-fidelity (Hi-Fi) home
: While similar to other STK411 models (like the 240E or 230E), always verify voltage requirements. For example, if a circuit specifies a 240V part, you should not downgrade to the 210V version. Reference Resources
While the exact per-channel wattage for the "210E" variant is often found in the full datasheet, the STK411 series generally covers an output range of 6W to 100W per channel
The STK411-210E is a highly sought-after power amplifier module designed and manufactured by Sanyo (now part of ON Semiconductor). This module is widely used in various audio applications, including home theaters, soundbars, and other audio equipment. In this article, we will provide an in-depth analysis of the STK411-210E datasheet, highlighting its key features, specifications, and applications.
