TDA7294V

Overview

The TDA7294V is a monolithic integrated circuit in a Multiwatt15 package, designed as an audio Class AB amplifier for Hi-Fi applications. It features a wide operating voltage range of ±10V to ±40V and delivers up to 100W music power into 4Ω or 8Ω loads. The device utilizes DMOS technology for high output current capability and includes built-in muting and standby functions with turn-on delay to prevent switching noises.

Feature Summary

• Integrates mute and standby control functions with turn-on delay to eliminate switching on/off noise
• Employs DMOS power stage technology combined with bipolar input stages for low distortion and high drive capability
• Includes comprehensive protection mechanisms such as thermal shutdown and short-circuit protection

Applications

• Home stereo systems
• Self-powered loudspeakers
• High-performance television sets

Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm package variant and electrical characteristics. Ensure compatibility with Multiwatt15 mounting requirements and verify that the selected component meets the required thermal dissipation standards for the intended application environment.

Selection Notes

Select this component for designs requiring high voltage tolerance and robust protection in single-channel audio amplification. Consider the Multiwatt15 package dimensions for PCB layout and ensure adequate heatsinking is provided to manage thermal load under maximum power conditions within the specified temperature range.

Part Context

Part of the TDA7294 series, this amplifier was developed to provide high-fidelity sound reproduction with simplified peripheral circuitry. It combines bipolar input stages with DMOS output stages to achieve superior performance metrics compared to earlier linear integrated circuits, making it suitable for demanding audio environments.
