Overview
The TPA0162PWPR is a stereo audio power amplifier from Texas Instruments, housed in a 24-pin HTSSOP thermally enhanced package. It delivers 2.8 W of continuous RMS power per channel into a 3-Ω load and supports up to 4-W peak output at 5 V. The device operates within a supply voltage range of 2.7 V to 5.5 V and features digital volume control via an I²C interface. It functions as a Class AB amplifier with a minimum operating temperature of -40°C and a maximum of +85°C.
Feature Summary
- Integrates digital volume control accessible through an I²C serial interface for system flexibility.
- Provides high-efficiency Class AB amplification suitable for battery-powered portable applications.
- Includes integrated soft-start functionality to minimize audible pop-and-hiss during power transitions.
Applications
- Portable media players
- Mobile phones
- Personal digital assistants
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging variant when sourcing. Confirm that the required I²C address configuration matches your system design. Ensure thermal management strategies account for the HTSSOP-24 package limitations under high-power conditions.
Selection Notes
Select this component for designs requiring integrated digital volume adjustment without external microcontrollers. It is appropriate for systems needing stereo output with minimal external passive components. Consider the 24-pin package size constraints relative to the available PCB real estate.
Part Context
This part belongs to the TPA0162 family of audio amplifiers. It is distinct from switching regulators like the TPS series or hot-swap controllers found in similar catalogs. The PWPR suffix specifically denotes the reel-packaged version of the TPA0162PWP.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material.
