TDA7293HS

Overview

The TDA7293HS is a monolithic integrated circuit in the Multiwatt15H package, designed as an audio Class AB amplifier for Hi-Fi applications. It utilizes Multipower BCD technology and features a DMOS power stage to deliver high output power into both 4-Ω and 8-Ω loads. The device supports a very high operating voltage range of ±50 V and includes built-in muting and standby functions with turn-on delay to prevent switching noises.

Feature Summary

• DMOS power stage utilizing Multipower BCD technology
• Built-in muting and standby functions with turn-on delay
• Short-circuit protection and thermal shutdown capabilities
• Clip detector and modularity for parallel connection

Applications

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

Procurement Notes

Verify that the specific suffix 'HS' corresponds to the Multiwatt15H package variant when sourcing components. Confirm the manufacturer datasheet specifies the exact pinout and thermal characteristics for this package style to ensure compatibility with existing PCB layouts and heat sinking requirements.

Selection Notes

Select this component for designs requiring high voltage operation up to ±50 V and robust protection against short circuits and thermal overload. The inclusion of a clip detector and low distortion characteristics makes it suitable for high-fidelity audio reproduction where signal integrity and system reliability are critical priorities.

Part Context

This part belongs to the TDA7293 series of high-power audio amplifiers manufactured by STMicroelectronics. It shares functional similarities with other members like the TDA7293V but differs in its physical packaging configuration, specifically utilizing the Multiwatt15H format which may offer distinct thermal or mounting advantages for specific enclosure designs.
