TAS5630BDKD

Overview

The TAS5630BDKD is a stereo Class-D and Class-G audio amplifier manufactured by Texas Instruments. It features analog input and integrated feedback via PurePath HD technology, delivering up to 300W per channel in stereo BTL configuration or 400W in mono PBTL mode. The device operates on a single 25V to 52.5V supply with a signal bandwidth exceeding 80kHz. Key electrical parameters include 0.03% THD+N at 1W into 4Ω, >100dB SNR (A-weighted), and 88dB PSRR. It utilizes a 44-pin HSSOP package.

Feature Summary

• Integrates PurePath HD closed-loop feedback technology for ultra-low distortion and high-fidelity audio performance comparable to traditional Class-AB amplifiers.
• Supports multiple output configurations including stereo bridge-tied load (BTL), mono parallel bridge-tied load (PBTL), and 2.1 systems with independent subwoofer drive.
• Features advanced self-protection mechanisms including under-voltage lockout, over-temperature shutdown, clipping detection, and short-circuit protection with error reporting.

Applications

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

Procurement Notes

Verify current availability status as the component may be discontinued or restricted. Confirm package integrity upon receipt due to moisture sensitivity classification. Ensure thermal interface material compatibility with the exposed pad design for optimal heat dissipation during operation.

Selection Notes

Select this model for applications requiring high-power stereo output with analog inputs. Consider the 44-pin HSSOP package constraints for PCB layout. Evaluate thermal management requirements carefully given the high power density and reliance on exposed pad cooling solutions.

Part Context

This part belongs to the TAS5630B series of high-performance digital audio power stages. It is designed to replace traditional linear amplifiers in high-end audio equipment, offering superior efficiency and reduced bill of materials through the elimination of large heatsinks and transformers.

Replacement Considerations

TAS5630PHD: Alternative package variant (HTQFP-64) with similar electrical characteristics but different physical footprint and thermal profile.
