TDA2030AV

Overview

The TDA2030AV is a monolithic integrated circuit in the Pentawatt package designed for low-frequency Class AB amplification. It supports a maximum supply voltage of ±22V and delivers up to 18W output power into an 8Ω load at ±19V. The device features high output current capability, very low harmonic distortion, and built-in thermal shut-down and short-circuit protection systems.

Feature Summary

• Integrated thermal shut-down system limits junction temperature to prevent damage during overload or excessive ambient temperatures.
• Short-circuit protection automatically limits dissipated power to maintain output transistors within their safe operating area.
• High output current capability with very low harmonic and crossover distortion characteristics.

Applications

• Active loudspeaker systems
• Musical instrument amplifiers
• Hi-Fi audio amplifiers

Procurement Notes

Verify the specific ordering suffix 'V' against the manufacturer's official documentation to confirm exact mechanical dimensions and pinout compatibility. Ensure that the selected Pentawatt package variant matches the required thermal resistance and mounting specifications for the intended application design.

Selection Notes

Select this component for applications requiring reliable operation without regulated power supplies due to its higher breakdown voltage tolerance. Consider the internal protection mechanisms when designing for environments prone to output shorts or thermal stress. Verify that the external component values align with the recommended closed-loop gain settings to ensure stability.

Part Context

This part belongs to the TDA2030A series of high-fidelity audio amplifiers manufactured by STMicroelectronics. It is engineered as a direct replacement for standard IC power amplifiers with lower voltage ratings, offering enhanced reliability for driver circuits using complementary pairs.

Replacement Considerations

Compatible substitutes include the TDA2030AH from the same series. Verify pin compatibility and thermal performance before substitution.
