TPA6113A2D

Audio Amplifiers Overview

The TPA6113A2D is a Class-AB stereo headphone amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and delivers up to 40 mW of output power per channel into a 16-ohm load. The device features a shutdown mode for power conservation and includes pop-and-click suppression circuitry to minimize audible transients during power-up and power-down sequences. It is housed in an 8-SOIC surface-mount package.

Audio Amplifiers Feature Summary

• Integrated pop-and-click suppression mechanism reduces audible transients during power transitions.
• Shutdown capability allows for significant power reduction when the device is not in use.
• Class-AB topology provides efficient stereo amplification for low-voltage portable applications.

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation, as ordering codes may indicate variations in packaging or tape-and-reel specifications that do not alter the electrical function. Confirm RoHS compliance status through the current datasheet. Ensure the selected package matches the intended PCB footprint design requirements.

Audio Amplifiers Selection Notes

Select this component for designs requiring low-voltage operation with integrated transient protection. The fixed gain configuration suits direct connection to line-level sources without external feedback networks. Consider the thermal performance within the SOIC-8 package relative to the expected continuous power dissipation in the target enclosure.

Audio Amplifiers Part Context

This part belongs to the TPA6113 series of audio amplifiers designed specifically for battery-powered consumer electronics. It serves as a compact solution for driving stereo headphones from single-cell lithium-ion or alkaline batteries, offering a balance between audio fidelity and power efficiency in space-constrained mobile devices.

Audio Amplifiers Replacement Considerations

The TPA6113A2DR is a verified substitute variant differing only in reel packaging configuration. Verify pinout compatibility before substitution.
