TDA7266P13TR

Overview

The TDA7266P13TR is a Class-AB dual bridge audio amplifier manufactured by STMicroelectronics. It delivers 4W output power into an 8-ohm load with a total harmonic distortion plus noise of 0.03%. The device operates on a single power supply ranging from 3.5V to 12V and features a gain of 26dB. It utilizes a PowerSSO-24 surface-mount package and supports through-hole installation styles in related variants within the series.

Feature Summary

• Dual bridge amplifier architecture for stereo audio applications
• Integrated short-circuit and thermal protection mechanisms
• Single-supply operation capability
• Low total harmonic distortion plus noise performance

Applications

• Portable audio equipment
• Miniature speaker systems
• Consumer electronics audio stages

Procurement Notes

Verify the specific suffix P13TR against official datasheets to confirm the PowerSSO-24 package and reel packaging configuration. Ensure compatibility with single-supply voltage ranges between 3.5V and 12V for the target application design.

Selection Notes

Select this component for designs requiring low-power stereo amplification with minimal external components. Consider the 4W output capability and 26dB fixed gain when matching input signal levels to drive 8-ohm loads efficiently within the specified voltage constraints.

Part Context

This part belongs to the TDA7266 series of audio power amplifiers, which includes various packages such as Multiwatt-15 and PowerSO-20. The series offers different output power ratings and voltage ranges, providing flexibility for diverse audio system requirements across consumer and industrial sectors.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series or other Class-AB dual bridge amplifiers with similar 4W output and 3.5V-12V operating ranges. Verify package dimensions and thermal characteristics before substitution.
