Overview
The TPA3005D2PHP is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 6 W of continuous output power into an 8-ohm load with 0.1% total harmonic distortion plus noise. The device operates on a single supply voltage ranging from 8.5 V to 18 V and features analog input. It is housed in a 48-pin HTQFP package and supports surface-mount installation. The operational temperature range spans from -40°C to +85°C, with a quiescent current of 11 mA.
Feature Summary
- Filter-free Class-D architecture eliminates the need for external output filters
- Stereo output configuration provides two-channel audio amplification
- Analog input interface allows direct connection to standard audio sources
Applications
- Portable multimedia devices requiring high-efficiency audio amplification
- Home theater systems utilizing filter-free Class-D designs
- Automotive infotainment units operating within specified voltage ranges
Procurement Notes
Verify the specific suffix 'PHP' against the manufacturer's official documentation to confirm the exact package variant and tape-and-reel specifications. Ensure that the ordering information matches the required thermal performance and pinout configuration for your PCB layout. Cross-reference the datasheet revision date to guarantee compatibility with your design requirements.
Selection Notes
Select this component when a stereo Class-D amplifier with 6 W output power is required. It is suitable for applications needing a single-supply operation between 8.5 V and 18 V. Consider the 48-pin HTQFP package for thermal management and board space constraints. Verify that the 0.1% THD+N specification meets your audio quality standards.
Part Context
This part belongs to the TPA3005D2 series of stereo audio amplifiers. It shares architectural similarities with other members like the TPA3004D2 but offers lower output power. The series is designed for filter-free implementations, reducing bill-of-materials complexity compared to traditional Class-AB amplifiers.
Replacement Considerations
The TPA3005D2PHPG4 is a lead-free version of this component. Verify if the RoHS compliance requirement necessitates the G4 suffix. Other series members may offer different power levels or package options.
