Overview
The TPA3002D2PHPG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 8.5 V to 14 V and delivers 9 W of output power into an 8-ohm load. The device features a total harmonic distortion plus noise (THD+N) of 0.025%. It utilizes a differential input configuration and is housed in a 48-pin HTQFP package. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Filter-free Class-D architecture for efficient audio amplification
- Integrated volume control functionality
- Differential input interface for improved noise immunity
Applications
- Stereo audio systems requiring medium power output
- Consumer electronics with limited space constraints
- Battery-powered audio devices
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the package type matches the design requirements, as variations exist within the series. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications to avoid handling discrepancies during assembly.
Selection Notes
Select this component when a stereo Class-D amplifier with integrated volume control is required. It is suitable for applications needing 9 W output at 8 ohms with low distortion. Consider the HTQFP-48 package for thermal management and pin count needs. Verify that the 8.5 V to 14 V supply range fits the system power design.
Part Context
This part belongs to the TPA3002D2 series of audio amplifiers. It shares architectural similarities with other members like the TPA3002D2PHPR but differs in packaging and compliance markings. The series is designed for high-efficiency audio applications, offering a balance between performance and complexity compared to linear amplifiers.
Replacement Considerations
The TPA3002D2PHPR is a direct functional substitute within the same series, differing primarily in reel packaging versus tube/tray options. Ensure compatibility with existing PCB footprints and thermal designs when substituting.
