TPA6130A2RTJR

Audio Amplifiers Overview

The TPA6130A2RTJR is a stereo headphone amplifier from Texas Instruments, utilizing Class-AB topology within a 20-WFQFN package. It delivers 138 mW of output power into a 16 Ohm load with a THD+N of 0.0027%. Operating on a single supply voltage ranging from 2.5 V to 5.5 V, the device draws 4 mA of quiescent current. It features differential inputs and supports a slew rate of 300 mV/us across an operating temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrates DirectPath technology for single-supply operation without output coupling capacitors.
• Includes I2C interface for digital volume control and configuration management.
• Provides comprehensive protection mechanisms including thermal shutdown and short-circuit protection.
• Features pop-and-click suppression circuitry to minimize audible transients during power-up and power-down.

Audio Amplifiers Applications

• Portable audio players
• Mobile phones
• Personal media players

Audio Amplifiers Procurement Notes

Verify the specific suffix RTJR against the manufacturer's official datasheet to confirm the reel packaging quantity and tape specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the QFN-20 footprint matches your PCB design guidelines before finalizing procurement orders.

Audio Amplifiers Selection Notes

Select this component when low total harmonic distortion is critical for high-fidelity audio reproduction in space-constrained designs. The integrated I2C interface simplifies system-level volume control compared to analog potentiometer solutions. Consider the 20-pin QFN package constraints regarding thermal dissipation and soldering processes for surface-mount assembly.

Audio Amplifiers Part Context

This part belongs to the TPA6130A2 series of stereo headphone amplifiers. It is distinct from other variants like the TPA6130A2YZHT, which utilizes a DSBGA-16 package instead of the QFN-20 form factor. The series is designed specifically for portable applications requiring high performance in small footprints.

Audio Amplifiers Replacement Considerations

The TPA6130A2RTJT serves as a verified alternative variant within the same family, differing primarily in its cut-tape packaging rather than electrical function. Verify pinout compatibility and thermal characteristics when substituting between different package types such as the DSBGA-16 variant.
