TDA7263

Overview

The TDA7263 is a Class AB dual audio power amplifier designed for high-quality sound applications. It operates within a wide supply voltage range of 10V to 30V and delivers up to 12W per channel into an 8Ω load at 28V with 10% THD. The device features built-in AC short-circuit protection, thermal overload protection, and a pop-free mute facility. Packaged in the Clipwatt-11 through-hole format, it includes a thermal shutdown circuit that activates at 145°C to prevent damage.

Feature Summary

• Class AB stereo architecture optimized for high-fidelity audio reproduction
• Integrated thermal shutdown mechanism preventing junction temperature exceeding 145°C
• AC short-circuit tolerance allowing resistance to accidental speaker connection errors
• Low consumption mute function providing pop-free operation

Applications

• HI-FI music centers
• Stereo TV sets

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the Clipwatt-11 outline dimensions. Ensure the specific part number variant aligns with required electrical characteristics before integration into final designs.

Selection Notes

Select this component for designs requiring robust thermal management and high output power in a single package. Verify that the application environment stays within the specified operating temperature range of 0°C to 70°C. Ensure adequate heatsinking is provided to maintain junction temperatures below the thermal shutdown threshold during peak operation.

Part Context

This component belongs to STMicroelectronics' line of discrete audio power amplifiers. It utilizes the proprietary Clipwatt package to facilitate efficient heat dissipation while maintaining a compact footprint suitable for consumer electronics. The design focuses on reliability and ease of implementation in standard stereo configurations.
