TDA2030H

Overview

The TDA2030H is a monolithic integrated circuit in a Pentawatt package designed for low-frequency Class AB audio amplification. It provides up to 14W output power at 14V/4Ω with 0.5% distortion, or 12W on a 4Ω load and 8W on an 8Ω load under ±14V conditions. The device features a supply voltage range of ±6V to ±18V (36V max), quiescent current of 40-60mA, and high output peak current limited internally to 3.5A. It incorporates patented short-circuit protection and thermal shut-down systems.

Feature Summary

• Integrated patented short-circuit protection system that limits dissipated power to maintain safe operating area
• Built-in thermal shut-down mechanism prevents damage by reducing power dissipation when junction temperature reaches 150°C
• Low harmonic and crossover distortion characteristics ensure high-fidelity audio performance
• High output current capability suitable for driving low impedance loads

Applications

• Low frequency Class AB audio amplifiers
• Hi-Fi audio amplifier circuits
• Single supply voltage configurations
• Bridge amplifier configurations with split power supply

Procurement Notes

Verify the specific ordering suffix 'H' against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS compliance standards if required by your design specifications. Confirm that the Pentawatt package type matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring reliable Class AB amplification with minimal external components. Consider the thermal resistance data when designing heatsink solutions, as maximum allowable power dissipation depends on ambient temperature and heatsink size. Verify input biasing and feedback network values to achieve desired closed-loop gain while maintaining stability.

Part Context

The TDA2030 series includes variants such as TDA2030V and TDA2030H, all utilizing the Pentawatt package. This family of devices is intended for use as low-frequency amplifiers providing high output current with very low distortion. The H variant specifically denotes the Pentawatt package configuration used in this datasheet.

Replacement Considerations

Other manufacturers produce functionally equivalent audio amplifiers with identical pinouts, including models from Vishay Telefunken and Unisonic Technologies. These alternatives typically share the same 5-pin Pentawatt package and electrical characteristics, allowing for direct substitution in existing designs without circuit modification.
