TPA6130A2RTJTG4

Audio Amplifiers Overview

The TPA6130A2RTJTG4 is a Class-AB stereo headphone amplifier from the DirectPath series by Texas Instruments. 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 between 2.5 V and 5.5 V, it draws 4 mA of quiescent current. The device features differential inputs, a slew rate of 300 mV/us, and integrated shutdown functionality. It is housed in a 20-QFN package and operates within a temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• DirectPath architecture eliminates external coupling capacitors for compact design
• Integrated volume control and mute functions via I2C interface
• Low distortion performance with high slew rate for accurate audio reproduction
• Built-in protection against short circuits and thermal overload

Audio Amplifiers Applications

• Mobile phone audio subsystems
• MP3 players and portable media devices
• Laptop computer audio outputs
• Portable gaming consoles

Audio Amplifiers Procurement Notes

Verify the G4 suffix indicates RoHS compliance and environmental standards. Confirm the QFN-20 package dimensions match your PCB footprint requirements. Ensure the differential input configuration aligns with your source impedance. Check that the operating voltage range covers your system's supply rails. Validate the thermal performance under maximum load conditions.

Audio Amplifiers Selection Notes

Select this component when low total harmonic distortion is critical for high-fidelity audio applications. The DirectPath topology is suitable for space-constrained designs requiring capacitor-free outputs. Consider the I2C control interface if digital volume adjustment is needed. The Class-AB operation offers a balance between efficiency and linearity for battery-powered devices.

Audio Amplifiers Part Context

This part belongs to the TPA6130A2 family of stereo headphone amplifiers. It shares core specifications with variants like TPA6130A2RTJR and TPA6130A2RTJT, differing primarily in packaging or reel configurations. The family is designed for portable electronics requiring high-quality audio playback with minimal external components.

Audio Amplifiers Replacement Considerations

TPA6130A2RTJR and TPA6130A2RTJT are functionally equivalent parts within the same series. Verify package compatibility before substitution as pinouts may differ slightly depending on the specific variant.
