Overview
The TPA2008D2PWPRG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and delivers up to 3W per channel into a 3-ohm load. The device utilizes a 24-pin PowerTSSOP package with a width of 4.40mm. It supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include differential input capability and integrated protection mechanisms against short circuits and thermal overload.
Feature Summary
- Integrates pop-and-click suppression circuitry to minimize audible noise during power-up and power-down transitions.
- Features differential input architecture for improved noise immunity in high-interference environments.
- Includes built-in thermal shutdown and short-circuit protection to ensure operational reliability under fault conditions.
Applications
- Portable multimedia speakers
- Desktop computer audio systems
- Personal media players
Procurement Notes
Verify the specific suffix G4 indicates RoHS compliance when sourcing components. Confirm the package type matches the 24-PowerTSSOP footprint requirements for the target PCB layout. Ensure the supply voltage constraints align with the system design before integration.
Selection Notes
Select this component for low-voltage applications requiring stereo output without external filters. Consider the thermal performance limits when designing for enclosed spaces. Verify that the 3-ohm load impedance matches the connected speaker specifications to achieve optimal power delivery.
Part Context
This part belongs to the TPA2008 series of Class-D amplifiers designed for portable audio applications. It serves as a compact solution for stereo sound reproduction in battery-powered devices. The series emphasizes efficiency and minimal external component count compared to linear amplifier alternatives.
Replacement Considerations
The TPA2008D2PWPR is the non-RoHS equivalent of this component. Verify pin compatibility and electrical specifications when substituting between these variants.
