Description
Professional-Grade Stereo Voltage Amplifier Module
The STK3082III is the elite "Series III" version of Sanyo’s precision thick-film hybrid integrated circuits. Designed as a voltage amplifier stage, this module is engineered to drive high-power output stages delivering between 80W and 90W per channel with unmatched signal purity.
Found in high-end vintage receivers and audiophile-grade integrated amplifiers, the STK3082III is prized for its ultra-low noise floor and improved thermal isolation, protecting your audio signal from internal interference.
Key Technical Features:
- Application: High-performance voltage amplification for 80W–90W power stages.
- Series III Advantage: Optimized internal current mirror for ultra-low Total Harmonic Distortion (typically 0.005%).
- Configuration: 2-Channel (Stereo) in a ZIP-15/SIP package.
- Voltage Stability: Built-in circuitry eliminates the need for external midpoint adjustments.
- Operating Voltage: Recommended ±50V (Absolute Maximum ±65V).
Technician's Note:
When installing the STK3082III, ensure that all output transistors and emitter resistors in the power stage are verified. Because this IC acts as the "driver," a short-circuit in the output transistors can backfeed and damage a new STK3082III immediately upon power-up.
Installation Tip: Use a high-quality thermal compound and ensure the metal backplate has full contact with the heatsink to maintain the "Series III" stability standards.
