TDA2050

The TDA2050 is a high-performance Class AB audio amplifier IC capable of delivering high output power with outstanding audio fidelity. Whether you’re upgrading a sound system, repairing subwoofers, or creating a DIY amplifier, this IC is a solid and reliable choice.

With a maximum output of up to 32W, the TDA2050 provides clear, distortion-free sound across a wide frequency range. Its low Total Harmonic Distortion (THD) and built-in safety protections make it suitable for both beginners and professionals looking for powerful yet stable performance in their audio projects.

Key Features & Specifications of the TDA2050

• Output Power: Up to 32W (with ±22V dual supply into 4Ω)
• Operating Voltage: ±4.5V to ±25V (dual) or up to 50V single supply
• Low Harmonic Distortion: < 0.05% THD at 1kHz
• Signal-to-Noise Ratio: > 90 dB
• Built-in Protections:
  • Short-circuit protection
  • Thermal shutdown
  • Safe Operating Area (SOA) protection
• Package: TO-220 5-pin package (ideal for mounting on heat sinks)
• Frequency Response: 20Hz to 20kHz – clean full-range sound reproduction

TDA2050 Applications

• Home audio systems
• Powered subwoofers and bookshelf speakers
• Car stereo amplifiers
• DIY audio projects and electronics education
