TDA7269A

Overview

The TDA7269A is a Class AB dual audio power amplifier designed for high-quality sound applications. It delivers 14W per channel into an 8-ohm load with 10% THD at ±16V supply. The device operates on split supplies ranging from ±5V to ±20V. Key electrical parameters include a gain of 80 dB, input bias current of 500 nA, and total harmonic distortion plus noise of 0.03%. It features integrated short-circuit protection to ground and thermal overload protection.

Feature Summary

• Integrated mute function eliminates pop noises during turn-on and turn-off operations
• Standby feature enables low quiescent current consumption
• Built-in short-circuit protection to ground safeguards the output stage
• Thermal overload protection prevents damage under excessive heat conditions

Applications

• Hi-Fi music centers
• Stereo television sets
• High-fidelity audio systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package variant and temperature range compatibility. Confirm RoHS compliance status through the latest product documentation. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Check for any recent lifecycle changes or obsolescence notices before finalizing procurement decisions.

Selection Notes

Select this component for stereo audio designs requiring moderate power output in consumer electronics. Ensure the application supports split supply voltages within the specified ±5V to ±20V range. Verify that the Multiwatt-11 package fits the thermal and spatial constraints of the target enclosure. Consider the need for external Boucherot cells if required by the specific speaker load characteristics.

Part Context

This component belongs to STMicroelectronics' TDA7269 series of audio amplifiers. It shares the Multiwatt-11 package form factor with related models like the TDA7265. The series targets the consumer audio market, offering a balance of performance and integrated protection features suitable for mass-produced electronic devices.

Replacement Considerations

The TDA7265 is a documented alternative within the same family, offering similar functionality with potentially different power ratings. Verify pinout compatibility and thermal requirements when substituting.
