) tie the input pins to the analog ground to establish the proper input bias current and input impedance match. 2. Negative Feedback (NFB) Network
: Operates on a split power supply, typically between ±15V and ±40V .
The is a classic, highly regarded two-channel thick-film hybrid audio power amplifier IC originally engineered by Sanyo . Renowned for its low harmonic distortion and robust output capability, this module was a staple in premium legacy stereo systems, such as the Sony HCD-GRX90 component system. Building or repairing an amplifier around this chip requires an in-depth understanding of its circuit diagram, power requirements, and pin configurations .

The STK411-210E is part of a larger family of hybrid ICs designed for ease of integration into audio platforms. Its architecture minimizes the need for external components by encapsulating complex stages—like biasing and output protection—within a single ZIP-22 package. 105W + 105W (at
If an STK411-210E circuit functions improperly, check for these typical warning signs:
Designed as a 2-channel AF power amplifier, it typically supports a split power supply. Building or repairing an amplifier around this chip
Handles low-level audio signals and sets the closed-loop gain block for Channel 1. Substrate Ground (GND)
The standard application circuit for the STK411-210E requires a split (dual) power supply ( ±VCCplus or minus cap V sub cap C cap C end-sub
The STK411-210E is a dual-channel power amplifier IC that operates on a single power supply voltage. It features a high output power, low distortion, and a wide range of operating voltages.
The output connects to your speakers (usually 6Ω or 8Ω loads). Because these chips can generate significant heat, the circuit diagram often incorporates:
: Hybrid circuits generate substantial concentrated heat during high-load periods. The module must be securely bolted to a large, finned aluminum heatsink using an even layer of high-grade zinc-oxide thermal paste.
