Overview
The TPA3004D2PHPRG4 is a stereo high-power filter-free Class-D audio power amplifier manufactured by Texas Instruments. It delivers 12 W of continuous output power into a 32-ohm load with a total harmonic distortion plus noise of 0.025%. The device operates on a single supply voltage ranging from 8.5 V to 18 V and features an integrated volume control function. It utilizes the HTQFP-48 package, supports surface-mount installation, and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Filter-free Class-D architecture eliminates external output filters for simplified design.
- Integrated digital volume control allows direct system interface without additional components.
- High efficiency operation reduces heat dissipation requirements in compact enclosures.
Applications
- Portable multimedia speakers
- Home theater systems
- Automotive infotainment amplifiers
Procurement Notes
Verify the specific suffix 'RG4' confirms RoHS compliance and lead-free status as per manufacturer specifications. Confirm the 'R' suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the ordering part number matches the required package variant and environmental rating for your production line.
Selection Notes
Select this component when a stereo Class-D solution with built-in volume adjustment is required. It is suitable for applications needing moderate power output into higher impedance loads like 32 ohms. Consider the HTQFP-48 package size for thermal management and PCB layout constraints compared to smaller alternatives.
Part Context
This part belongs to the TPA3004D2 series of audio amplifiers. It is a lead-free, RoHS-compliant version of the standard TPA3004D2PHPR, distinguished by the 'G4' suffix indicating enhanced environmental compliance and terminal finish specifications defined by Texas Instruments.
Replacement Considerations
Direct pin-compatible substitutes include the TPA3004D2PHPG4 (tray packaging) or the non-RoHS TPA3004D2PHPR. Verify that any replacement maintains the same 48-pin HTQFP footprint and electrical characteristics for seamless integration.
