TAS5611PHD

Overview

The TAS5611PHD is a Class-D audio amplifier manufactured by Texas Instruments, housed in a 64-pin HTQFP package. It delivers 125 W stereo or 250 W mono output with a THD+N of 0.03%. Operating on a 12 V to 32.5 V supply, it supports differential and single-ended inputs. The device functions within a temperature range of 0°C to +150°C and draws 20 mA of operating current.

Feature Summary

• PurePath HD analog-input power stage architecture
• Configurable for stereo or mono bridge-tied load operation
• Integrated thermal and short-circuit protection mechanisms

Applications

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

Procurement Notes

Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Validate that the specific revision matches your schematic requirements due to potential lifecycle changes.

Selection Notes

Select this component when high output power is required from an analog input source. Ensure the design accommodates the large HTQFP-64 footprint and adequate thermal dissipation for the 150°C junction capability. Verify compatibility with the 12V to 32.5V supply rail constraints.

Part Context

This part belongs to the TAS5611 series of PurePath HD amplifiers. It serves as a high-performance power stage solution for demanding audio applications. The PHD suffix indicates the specific surface-mount tray packaging variant within the broader product family.
