TAS5634DDVR

Overview

The TAS5634DDVR is a Texas Instruments digital-input Class-D audio amplifier power stage. It delivers up to 600W in mono or 300W in stereo configurations. The device operates with a supply voltage range of 12V to 58V. It features PurePath HD digital input technology for high-fidelity audio reproduction. The component is housed in an HTSSOP-44 package.

Feature Summary

• Supports digital input interfaces for direct connection to digital audio sources
• Provides high-efficiency Class-D amplification architecture
• Capable of driving low-impedance loads such as 3-ohm speakers

Applications

• High-power home theater systems
• Professional audio amplifiers
• Active loudspeaker designs

Procurement Notes

Verify the specific suffix DDVR against official datasheets to confirm pinout and thermal pad configuration. Ensure compatibility with the intended PCB layout, particularly regarding the HTSSOP-44 package dimensions. Confirm that the supply voltage requirements align with the system design before procurement.

Selection Notes

Select this component when high output power is required from a digital audio source. It is suitable for applications needing efficient amplification without external analog pre-amplification stages. Consider thermal management solutions due to the high power density of the device.

Part Context

This part belongs to the TAS563x family of high-power audio amplifiers. It is designed to replace older analog-input stages by integrating digital filtering and modulation directly on-chip. The TAS5634 offers higher power capabilities compared to lower-tier models in the same series.
