TAS5630BPHDR

Overview

The TAS5630BPHDR is a high-performance analog input Class-D and Class-G audio amplifier manufactured by Texas Instruments. It utilizes PurePath HD integrated feedback technology to deliver up to 300 W of stereo output power or 400 W in mono configuration. The device operates on a single 50 V supply and supports load impedances of 2 Ohms and 4 Ohms. Key electrical specifications include a THD+N of 0.03%, a signal bandwidth up to 80 kHz, and an operating temperature range from 0°C to +70°C. It is housed in a 64-pin HTQFP package with an exposed pad for thermal management.

Feature Summary

• Integrates PurePath HD closed-loop feedback technology to maintain low distortion levels comparable to traditional AB amplifiers while preserving D-class efficiency.
• Features a highly efficient power stage with 60mΩ output MOSFETs that achieve efficiency greater than 88%.
• Includes comprehensive self-protection mechanisms such as under-voltage lockout, over-temperature protection, clipping detection, and short-circuit protection with error reporting.

Applications

• Mini component systems
• AV receivers
• DVD receivers
• Active speakers

Procurement Notes

Verify the specific suffix PHDR to confirm the HTQFP-64 package type and reel packaging format. Ensure compatibility with the required thermal interface material between the exposed pad and heatsink to achieve rated power levels. Confirm RoHS compliance status and moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when high-fidelity audio reproduction with ultra-low THD is required alongside high power output. The integrated feedback loop simplifies design by reducing the need for external compensation networks. Consider the thermal constraints of the HTQFP-64 package and ensure adequate PCB copper area for heat dissipation to support continuous operation at maximum power.

Part Context

This part belongs to the TAS5630B series of PurePath HD analog-input power stages. It is designed for applications demanding both high power and high fidelity. The series offers flexibility through multiple configuration options including stereo BTL, mono PBTL, and multi-channel setups using the same core architecture.

Replacement Considerations

The TAS5630BDKD is a pin-compatible alternative within the same family but uses a 44-pin HSSOP package. Verify if the reduced pin count and different thermal characteristics meet the specific application requirements before substitution.
