TPA122DGNRG4

Overview

The TPA122DGNRG4 is a stereo audio power amplifier manufactured by Texas Instruments. It delivers 150 mW of output power per channel into an 8-ohm load. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. It features a Class-AB topology with fully differential inputs and outputs. The component is housed in an 8-pin MSOP package with an exposed PowerPad for thermal management. It supports PC power supply compatibility and includes short-circuit protection.

Feature Summary

Stereo audio amplification with 150-mW output capability
Fully differential input and output architecture
Compatible with PC power supply standards
Integrated short-circuit protection

Applications

Personal computers and notebooks
Portable multimedia devices
Low-power audio systems

Procurement Notes

Verify the complete part number including the RG4 suffix to ensure compliance with RoHS directives and lead-free manufacturing specifications. Confirm the MSOP-8 package variant matches the design requirements. Cross-reference the datasheet revision to ensure all electrical characteristics align with the current production version before finalizing procurement.

Selection Notes

Select this component for applications requiring stereo amplification in compact form factors. The MSOP-8 package with exposed pad is suitable for space-constrained designs. Ensure the system power supply remains within the 2.5 V to 5.5 V range. Consider the thermal performance provided by the PowerPad for sustained operation under load conditions.

Part Context

This part belongs to the TPA122 family of audio amplifiers from Texas Instruments. It is designed as a low-power solution for consumer electronics. The device integrates necessary protection features to enhance reliability in portable applications. It serves as a direct replacement for older stereo amplifier solutions in similar power classes.

Replacement Considerations

The TPA122DG4 is a non-RoHS compliant alternative within the same series. Verify pinout compatibility when substituting with other stereo amplifiers in the 8-pin MSOP package.
