TAS5611APHD

Overview

The TAS5611APHD is a Class-D audio amplifier power stage manufactured by Texas Instruments. It delivers 125 W stereo or 250 W mono output into 4-ohm loads and 250 W stereo or 500 W mono into 2-ohm loads. The device operates with a supply voltage range of 16 V to 34.1 V. It features a total harmonic distortion plus noise (THD+N) of 0.03%. The component is housed in a 64-pin HTQFP package and supports analog input signals.

Feature Summary

• PurePath HD architecture for high-fidelity audio reproduction
• Integrated analog input power stage eliminating external digital processing
• High efficiency Class-D operation reducing thermal management requirements

Applications

• Home theater systems
• Professional audio amplifiers
• Active loudspeaker designs

Procurement Notes

Verify the specific suffix 'PHD' to confirm the tape-and-reel packaging variant, as the tray-packaged 'PHDR' or other variants may differ in handling. Confirm RoHS compliance status through the official datasheet before procurement. Ensure the design accounts for the specified operating temperature range of 0°C to +70°C for this specific package type.

Selection Notes

Select this component when a high-power analog-input solution is required without complex digital signal processing integration. Compare against the TAS5611A series for pinout compatibility. Verify that the system power supply can support the maximum 34.1 V requirement and that the load impedance matches the rated output power specifications.

Part Context

This part belongs to the TAS5611 family of PurePath HD audio amplifiers. It serves as a high-power bridge-tied load (BTL) amplifier designed for demanding audio applications. The family includes variants with different packaging options such as PHD and PHDR, sharing core electrical characteristics but differing in physical form factor and shipping configuration.

Replacement Considerations

The TAS5611APHDR is a direct functional substitute with identical electrical specifications but differs in packaging format. Other TAS5611 variants may require schematic review due to potential differences in thermal performance or pin assignments.
