TPA0162PWPG4

Overview

The TPA0162PWPG4 is a 2.8-W stereo audio power amplifier manufactured by Texas Instruments, housed in a 24-pin HTSSOP package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device delivers 2.8 W per channel into a 3-Ω load. Key electrical characteristics include integrated digital volume control, input multiplexer functionality, and thermal protection circuitry. It supports differential inputs and includes features such as depop, mute, and shutdown modes to enhance system performance and user experience.

Feature Summary

• Integrates digital volume control and input multiplexer for simplified system design
• Provides thermal protection and pop-and-click suppression for reliable operation
• Supports differential inputs with dedicated mute and shutdown control pins

Applications

• Portable multimedia devices requiring high-fidelity stereo audio output
• Desktop speakers and home audio systems
• Automotive infotainment systems

Procurement Notes

Verify the component status as End-of-Life (EOL) or limited availability through official Texas Instruments channels before procurement planning. Confirm the specific suffix PG4 indicates lead-free and RoHS compliance. Ensure compatibility with existing PCB footprints for the 24-HTSSOP package. Request current production status documentation directly from the manufacturer to avoid obsolescence risks.

Selection Notes

Select this component when a stereo amplifier with integrated digital control is required. It is suitable for applications needing 2.8 W output into low-impedance loads like 3-Ω speakers. Consider the 24-pin HTSSOP package constraints for board space. Verify that the system supply voltage remains within the 4.5 V to 5.5 V range for optimal performance and safety margins.

Part Context

This part belongs to the TPA0162 family of audio power amplifiers. It is designed for stereo applications with integrated digital interfaces. The PWPG4 designation specifies the plastic heat sink package type and environmental compliance. It serves as a solution for mid-power audio requirements in consumer electronics.

Replacement Considerations

Consult Texas Instruments for current active replacements. Check for pin-compatible alternatives within the same product family if available. Verify functional equivalence regarding output power and control interfaces.
