TDA7266D13TR

Overview

The TDA7266D13TR is a dual bridge audio amplifier from STMicroelectronics, designed for applications such as LCD TVs, monitors, PC motherboards, and portable audio devices. It operates on a single supply voltage ranging from 3.5V to 12V. The device delivers an output power of 5W per channel at THD=10% with an 8-ohm load and 9.5V supply. It features internally fixed gain, eliminating the need for external bootstrap or Boucherot cells. Key protection mechanisms include thermal overload and short circuit protection.

Feature Summary

• Integrated thermal overload and short circuit protection for enhanced reliability
• Single-supply operation capability simplifying circuit design
• Internal fixed gain configuration reducing external component count
• Standby and mute functions for power management

Applications

• LCD TV systems
• Monitor audio circuits
• PC motherboard audio integration
• Portable audio equipment

Procurement Notes

Verify the specific suffix 'D13TR' against official STMicroelectronics documentation to confirm tape-and-reel packaging and exact pinout compatibility. Ensure the selected variant matches the required operating voltage range and thermal specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring a compact dual bridge amplifier with minimal external passive components. Consider its suitability for low-voltage single-supply systems where thermal protection and standby modes are critical. Verify that the 5W output per channel meets the acoustic requirements of the intended speaker configuration.

Part Context

This part belongs to the TDA7266 series of audio amplifiers by STMicroelectronics. The series includes various packages and configurations tailored for consumer electronics. The TDA7266D13TR specifically denotes a version optimized for surface-mount assembly in space-constrained portable and display devices.

Replacement Considerations

Consult official substitution lists for compatible alternatives within the TDA7266 family or equivalent dual bridge amplifiers from other manufacturers. Ensure any replacement maintains the same voltage range, pinout, and protection features.
