TDA7295

Overview

The TDA7295 is a monolithic integrated circuit in Multiwatt15 package, designed as an audio Class AB amplifier for Hi-Fi applications. It features a DMOS power stage with a bipolar differential input. Operating on dual supplies from ±10V to ±40V, it delivers up to 80W into 8Ω loads at THD=10%. Key electrical parameters include a typical THD+N of 0.005%, open-loop gain of 80 dB, and input impedance of 100 kΩ. The device supports high output current capability and includes built-in mute/stand-by functions.

Feature Summary

• Integrates mute and stand-by functions with turn-on delay to eliminate switching noises during remote operation.
• Features thermal shutdown and short-circuit protection mechanisms for enhanced operational reliability.
• Utilizes a DMOS power stage combined with a bipolar differential input for low distortion performance.
• Operates without requiring Boucherot cells for stable operation under standard load conditions.

Applications

• Home stereo systems
• Self-powered loudspeakers
• Top-class television audio systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging type and tape/reel specifications. Ensure the component matches the required Multiwatt15 pinout configuration for your PCB layout. Cross-reference the RoHS compliance status and REACH SVHC declarations with the latest datasheet revision to meet regulatory requirements for your target market.

Selection Notes

Select this component for designs requiring high voltage tolerance and significant power delivery in a single-channel mono configuration. The wide operating voltage range allows flexibility in power supply design. Consider the thermal management requirements associated with the Multiwatt15 package when designing for maximum power output scenarios.

Part Context

Manufactured by STMicroelectronics, the TDA7295 is part of their legacy audio amplifier portfolio. It utilizes DMOS technology to achieve high efficiency and power density. The device is intended for replacement or new designs in consumer audio equipment where robust protection features and high fidelity are prioritized.

Replacement Considerations

The TDA7294 is a related device offering higher power capabilities (up to 100W) within the same family. Verify pin compatibility and thermal characteristics if substituting between these models.
