Stereo 150W Class D Amp Module

Physical dimensions: 77 mm (L) × 73 mm (W) × 16 mm (H). Compatible with DC power inputs from 12 volts to 26 volts. Maximum combined stereo output: 150W (e.g., 75W per channel into 4Ω at typical operating voltage). Uses TPA3116D2 chipset for efficient Class D amplification. Includes integrated pre-preamp stage to boost signal-to-noise ratio and suppress electromagnetic interference from audio cables. PCB design prioritises thermal dissipation and signal path isolation, supporting reliable operation in continuous-use scenarios. This module is purpose-built for users who need meaningful power in minimal space — whether upgrading vintage hi-fi cabinets, adding clean gain to factory car speakers, or creating lightweight battery-powered audio gear. Its stable behaviour across varying supply voltages makes it especially suited for mobile applications where battery voltage fluctuates during operation. Typical implementations include active speaker conversions, compact stage monitor builds, educational electronics labs, and custom headphone amplifier hybrids (when paired with appropriate DAC and output stage). No external heat sinks required for moderate duty cycles; ventilation recommended for sustained high-output use.
