Description

The TDA2030 is a monolithic integrated circuit in a TO-220-5 package designed for use as a class AB audio amplifier. It can deliver up to 18W of output power into a 4Ω load with a single power supply or up to 35W into an 8Ω load in a bridge configuration with a dual power supply. The IC is known for its high output power, low distortion, and minimal external component requirements, making it a versatile solution for high-quality audio amplification.

The TDA2030 features built-in protection circuits, including short-circuit, thermal shutdown, and overvoltage protection, which ensure reliable and safe operation in various conditions.

Features

  • High Output Power:
    • 18W into 4Ω with a single power supply.
    • Up to 35W in bridge mode with dual supplies.
  • Low Distortion: Provides excellent audio quality with low Total Harmonic Distortion (THD), typically 0.1% at 14W output.
  • Wide Supply Voltage Range: Operates with a wide range of supply voltages, from ±6V to ±18V in dual supply mode or from 12V to 36V in single supply mode.
  • High Stability: Stable operation with high output voltage swing.
  • Built-in Protection:
    • Short-Circuit Protection: Protects the IC and connected components in the event of a short circuit.
    • Thermal Shutdown: Automatically shuts down the IC to prevent overheating.
    • Overvoltage Protection: Prevents damage from supply voltage spikes.
  • Wide Frequency Response: Provides good audio fidelity across a broad frequency range.
  • Minimal External Components: Requires few external components, simplifying circuit design and reducing cost.
  • Compact TO-220-5 Package: The package design allows for efficient heat dissipation and easy mounting to a heatsink.
