TDA7294 100 +100 Watt Stereo Amplifier Board PCB only

TDA7294 100 + 100 Watt Stereo Audio Amplifier PCB Board (Bare PCB)

This PCB is designed for building a stereo audio amplifier using TDA7294 or compatible ICs. Output performance depends on components used and assembly quality.

Output Power:

• Stereo output: up to 100 W + 100 W (depends on supply voltage, load, and heat dissipation)

Working Voltage:

• Dual supply: ±18 V to ±35 V DC
• Recommended transformer: 24-0-24 VAC, 5 A (step-down)

IC Compatibility:

• Supports TDA7293, TDA7294, TDA7295, TDA7296 (pin-to-pin compatible)

Speaker Compatibility:

• Supports 4 Ω and 8 Ω speaker loads
• Suitable for high-power stereo audio applications

Configuration:

• Designed for dual-rail DC operation using a center-tapped transformer
• Compact PCB layout for enclosure integration
• Requires proper heat sinking and component selection

Construction:

• Bare PCB (components not included)
• Designed for through-hole components

Intended Use:

• Stereo audio amplifier construction
• Subwoofer and full-range speaker systems
• Musical instrument amplification (e.g., guitar and similar audio sources)
• DIY audio amplifier projects
