TPA3139D2RGER

Overview

The TPA3139D2RGER is a Class-D stereo audio amplifier manufactured by Texas Instruments. It delivers 10 W of output power into an 8-ohm load, operating within a supply voltage range of 3.5 V to 14.4 V. The device features a total harmonic distortion plus noise (THD+N) of 0.04% and supports gain configurations of 20 dB or 26 dB. It utilizes a VQFN-24 package with surface-mount installation. The operational temperature range spans from -10°C to +85°C, with a maximum output current of 3.5 A and a quiescent current of 22.8 mA.

Feature Summary

• Inductor-free stereo architecture eliminates the need for external inductors, simplifying printed circuit board layout and reducing component count.
• High-efficiency Class-D operation minimizes thermal dissipation while maintaining low total harmonic distortion plus noise performance.
• Integrated protection mechanisms safeguard against short circuits, over-temperature conditions, and excessive ripple on the power supply line.

Applications

• Portable multimedia speakers
• Home theater systems
• Audio amplification modules

Procurement Notes

Verify the specific suffix RGER confirms the reel packaging format upon ordering. Confirm RoHS compliance status through official documentation before integration. Ensure the VQFN-24 footprint matches the target design constraints. Validate humidity sensitivity handling procedures during assembly. Cross-reference the datasheet for exact pinout definitions to prevent soldering errors.

Selection Notes

Select this component when designing stereo audio systems requiring high efficiency without inductive components. The wide supply voltage range accommodates various battery-powered applications.
