TDA729913TR

Overview

The TDA729913TR is a monolithic integrated circuit audio amplifier manufactured by STMicroelectronics. It operates in Class AB configuration and provides single-channel (mono) output. The device is housed in an 8-SOIC surface-mount package with dimensions of 0.154 inches (3.90mm) width. It functions within a supply voltage range of 4.5V to 18V. The amplifier delivers a maximum output power of 2W into an 8-ohm load. It includes built-in protection features such as pop-noise elimination, short-circuit protection, thermal shutdown, and standby mode. The component is rated for operation between 0°C and 70°C ambient temperature.

Feature Summary

• Class AB mono audio amplification
• Integrated pop-noise elimination and mute/standby control
• Short-circuit and thermal protection mechanisms

Applications

• Single-channel audio systems
• Low-power speaker drivers
• Consumer electronics requiring compact mono amplification

Procurement Notes

Verify the specific suffix '13' against official STMicroelectronics documentation to confirm pinout and functional compatibility, as variations exist within the TDA7299 family. Confirm the 8-SOIC package type matches the design footprint. Check current lifecycle status, as this part may be discontinued or subject to last-time buy restrictions. Ensure the TR tape-and-reel packaging aligns with automated assembly requirements.

Selection Notes

Select this component for applications requiring a simple, low-cost mono amplifier solution. It is suitable for designs where power output requirements are modest, specifically around 2W into 8 ohms. The 8-SOIC package offers a compact form factor for space-constrained boards. Consider the 4.5V to 18V supply range when designing the power stage. Verify that the thermal management strategy supports the expected dissipation levels at the target operating temperature.

Part Context

This part belongs to the TDA7299 series of audio amplifiers from STMicroelectronics. The series typically includes variants with different channel counts and power outputs. The TDA729913TR specifically denotes the mono, 8-SOIC version. Other members of the family may offer stereo configurations or higher power capabilities in different packages like PowerSO-20 or Multiwatt.

Replacement Considerations

Direct substitutes include other TDA7299 series variants if pinouts match, such as TDA7299D or TDA7299A, but verification of the specific suffix is required. Cross-reference with generic Class AB mono amplifiers only if electrical parameters and package dimensions are identical.
