Overview
The TAS5766MRMTT is a stereo Class-D audio amplifier from the Texas Instruments PurePath Smart Amp series. It delivers up to 50 W of output power into a 4-ohm load. The device operates within a supply voltage range of 4.5 V to 26.4 V and maintains a total harmonic distortion plus noise (THD+N) of 0.05%. It utilizes a VQFN-48 package for surface-mount installation. The component supports an operating temperature range from -25°C to +85°C.
Feature Summary
- Integrates PurePath Smart Amp technology for closed-loop digital control and real-time speaker protection.
- Features ternary modulation architecture designed to optimize efficiency and audio fidelity.
- Supports I2S digital input interface for direct connection to digital audio sources.
Applications
- Smart speakers and voice-controlled audio hubs
- Portable Bluetooth speakers and wireless audio devices
- Home theater soundbars and AV receivers
Procurement Notes
Verify the specific suffix 'TT' against the official Texas Instruments datasheet to confirm tape-and-reel specifications and moisture sensitivity level. Ensure compatibility with the required PCB footprint for the VQFN-48 package during procurement planning.
Selection Notes
Select this component when high-efficiency stereo amplification is required for battery-powered or low-voltage systems. The integrated smart amp features simplify thermal management and eliminate the need for external analog protection circuits, reducing overall bill of materials complexity.
Part Context
This part belongs to the TAS5766M family of high-performance audio amplifiers. It shares core architectural similarities with variants like the TAS5766MRMTR but differs in packaging configuration and reel specifications. The family is designed for applications demanding high power density and advanced digital signal processing capabilities.
Replacement Considerations
The TAS5766MRMTR is a verified alternative within the same product family. Verify pin-to-pin compatibility and ensure the replacement meets the specific thermal and electrical requirements of the target application.
