TDA7265B

Overview

The TDA7265B is a dual Class-AB audio power amplifier manufactured by STMicroelectronics, housed in an 11-pin Multiwatt package. It delivers 30W of stereo output power with a maximum supply voltage of 35V. The device integrates comprehensive protection mechanisms including thermal overload and short-circuit safeguards. It supports mute and standby functions to eliminate pop noise during operation.

Feature Summary

• Dual-channel Class-AB architecture for high-fidelity stereo amplification
• Integrated thermal overload and short-circuit protection circuits
• Mute and standby features enabling low quiescent current consumption

Applications

• High-quality sound applications such as Hi-Fi music centers
• Stereo television sets requiring robust audio processing
• Consumer electronics demanding reliable stereo amplification

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and electrical ratings. Ensure the Multiwatt-11 package matches the target PCB footprint. Confirm RoHS compliance status prior to integration into final assemblies.

Selection Notes

Select this component for designs requiring dual-channel amplification without digital interfaces. It suits single-supply implementations where thermal management is feasible via the exposed pad. Evaluate power dissipation requirements against the available heatsinking area on the printed circuit board.

Part Context

This part belongs to the TDA7265 series of audio power amplifiers. It shares architectural similarities with variants like the TDA7265A but may differ in specific electrical tolerances or packaging configurations. The series targets consumer audio markets rather than automotive environments.

Replacement Considerations

Check for direct substitutes within the same product family. Verify that any alternative maintains identical pin assignments and thermal characteristics to ensure seamless replacement without redesigning the host circuit.
