TAS5611PHDR

Overview

The TAS5611PHDR is a high-performance Class-D audio power stage from Texas Instruments' PurePath HD series. It delivers 125W per channel in stereo mode and 250W in mono mode. The device operates with supply voltages ranging from 18V to 38V. It features analog inputs and is housed in a 64-pin HTQFP package with exposed pad for thermal management. The component supports differential input configurations and includes protection mechanisms against short circuits and thermal overload.

Feature Summary

• PurePath HD architecture providing high efficiency and low distortion
• Analog input interface for direct connection to source components
• Integrated protection circuitry including thermal foldback and short-circuit protection

Applications

• High-fidelity home theater systems
• Professional audio amplification equipment
• Active loudspeaker designs requiring high power output

Procurement Notes

Verify the specific suffix PHDR to confirm the tape and reel packaging format and pin configuration. Confirm that the analog input variant matches the system design requirements, as digital input versions exist within the same family. Check current lifecycle status as older revisions may be obsolete or recommended for non-new designs.

Selection Notes

Select this component when analog input control is preferred over digital interfaces. Ensure the power supply rail can support the required voltage range up to 38V. Verify that the PCB layout accommodates the 64-HTQFP package dimensions and provides adequate thermal dissipation for the exposed pad to handle the high power output capabilities.

Part Context

This part belongs to the TAS5611 family of high-power audio amplifiers. It is distinct from digital-input variants like the TAS5611A which require external digital processors. The PHDR suffix indicates a specific packaging and shipping configuration compared to other suffixes in the product line.
