Description
Specialized 6W Stereo TV Audio Power Amplifier
The STK4101IITV is a dedicated version of Sanyo’s 6W+6W stereo hybrid IC, specifically designed for television audio output stages. While it maintains the classic "Series II" performance standards, the TV-suffix signifies its optimization for the unique thermal and electrical environments found inside television chassis.
This module is the ideal replacement part for restoring sound in vintage CRT televisions and early integrated TV/Audio units. It features Sanyo’s thick-film technology, ensuring a stable 6 Watts per channel with the low harmonic distortion required for clear dialogue and music reproduction.
Key Technical Features:
- Continuous Power Output: 6W + 6W (at 8Ω, THD = 0.4%)
- Optimized Application: Screened for TV audio output reliability.
- Configuration: 2-Channel Stereo (18-Pin SIP Package).
- Voltage Capability: Designed for split power supply use (Recommended ±13.2V).
- Low Noise: Features an internal constant current circuit to minimize hum and ripple noise common in TV power supplies.
Installation & Compatibility:
The STK4101IITV is pin-compatible with the standard STK4101II. However, technicians should note that the "TV" variant may have specific lead forming or internal tolerances optimized for television circuit boards. Always ensure a clean application of thermal grease to the backplate before securing it to the internal chassis heatsink.
Technician's Note: TV audio circuits are often subject to high ambient internal temperatures. Verify that the surrounding electrolytic capacitors are healthy, as they are the primary cause of driver IC failure in television units.
