Description
Ultimate-Grade 100W Mono Power Amplifier Module
The STK4044X is the highest-specification thick-film hybrid integrated circuit in Sanyo's 100W mono lineup. Engineered for clinical accuracy and absolute signal purity, the "X" series represents the pinnacle of hybrid amplification. It delivers a continuous 100 Watts of power with an industry-leading Total Harmonic Distortion (THD) of just 0.008%.
This module is the definitive choice for audiophile mono-block builds, high-end center channel restorations, and premium active monitors where zero signal coloration is required. Its advanced internal cascode and current mirror circuitry provide a noise floor that is virtually silent.
Key Technical Features:
- Continuous Power Output: 100W min (at 8Ω, 20Hz to 20kHz, THD = 0.008%).
- Master-Grade Distortion: 0.008% THD for unmatched sonic transparency.
- Configuration: Mono (Single Channel) in an 15-pin hybrid package.
- Frequency Response: Optimized for high-bandwidth audio from 20Hz to 50kHz.
- Operating Voltage: Recommended supply of ±51V (Absolute Maximum ±74V).
- Stability: Enhanced thermal tracking and internal compensation for professional reliability.
Installation & Thermal Management:
Due to its high-precision architecture and 100W output, the STK4044X must be mounted to a substantial, high-mass heatsink using premium thermal grease. Operating the module without a heatsink—even for a few seconds—will result in immediate and permanent internal substrate failure.
Technician's Note: Verify that your power supply rails are healthy and balanced at ±51V. For the best performance from this "X" series chip, we recommend using high-quality low-ESR filtering capacitors in the power stage to maintain the ultra-low 0.008% THD specification.
