Overview
The TPA3004D2PHPG4 is a stereo high-power filter-free Class-D audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 8.5 V to 18 V and delivers 12 W of output power into a 32-ohm load. The device features a total harmonic distortion plus noise (THD+N) of 0.025% and channel separation of 77 dB. It utilizes a 48-pin HTQFP package, supports surface mount installation, and functions across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrated volume control functionality for direct system integration
- Filter-free Class-D architecture simplifies external component requirements
- Stereo output configuration with dedicated shutdown capability
Applications
- High-fidelity stereo audio systems
- Consumer electronics requiring integrated volume adjustment
- Battery-powered devices utilizing single-supply operation
Procurement Notes
Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the HTQFP-48 package dimensions match your PCB footprint requirements. Ensure the 8.5 V to 18 V supply voltage aligns with your system design constraints before finalizing procurement orders.
Selection Notes
Select this component when a stereo Class-D amplifier with built-in volume control is required. It is suitable for applications needing 12 W output into 32-ohm loads. Consider the 48-pin HTQFP package for surface-mount assembly. Verify thermal management capabilities for the intended operating environment.
Part Context
This part belongs to the TPA3004D2 series of audio amplifiers from Texas Instruments. The series includes variants such as TPA3004D2PHPR and TPA3004D2PHP. These devices are designed for high-performance audio applications requiring efficient power delivery and low distortion characteristics in compact form factors.
Replacement Considerations
TPA3004D2PHP and TPA3004D2PHPR are related parts within the same family. Verify if the packaging type (Tray vs. Reel) or specific RoGS compliance status meets your manufacturing needs.
