TAS5733LDCA

Overview

The TAS5733LDCA is a stereo Class-D audio amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 8V to 16.5V and delivers 10W per channel into an 8-ohm load in stereo mode, or 20W mono output. The device utilizes a digital interface for control and signal input. It is housed in a 48-pin PowerTFSOP package with dimensions of 0.240 inches (6.10mm) width. The component supports operation at ambient temperatures between 0°C and 85°C.

Feature Summary

• Integrated protection mechanisms including short-circuit and thermal shutdown capabilities.
• Built-in pop-and-click suppression circuitry to minimize audible noise during power transitions.
• Digital interface compatibility for simplified system integration and control.

Applications

• Portable speaker systems requiring high efficiency and compact form factors.
• Home audio equipment utilizing stereo Class-D amplification.
• Automotive infotainment sub-systems compatible with specified voltage ranges.

Procurement Notes

Verify the specific suffix 'LDCA' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure that the 48-PowerTFSOP footprint matches your PCB design constraints. Confirm moisture sensitivity level (MSL 3) requirements for your assembly process. Cross-reference the ordering part number with official Texas Instruments documentation to avoid substitution errors.

Selection Notes

Select this component when a stereo Class-D amplifier with digital input is required for applications operating between 8V and 16.5V. It is suitable for designs needing 10W per channel into 8-ohm loads. Consider the 48-pin PowerTFSOP package for thermal management and space efficiency. Verify compatibility with your system's digital audio interface protocols before finalizing the design.

Part Context

The TAS5733 belongs to Texas Instruments' portfolio of efficient Class-D audio amplifiers designed for portable and fixed audio applications. This series emphasizes high power output relative to size and includes integrated protection features. The LDCA variant specifically denotes the 48-pin PowerTFSOP packaging option, distinguishing it from other package configurations within the same functional family.

Replacement Considerations

Consult the Texas Instruments TAS5733 datasheet for officially listed alternative packages or pin-compatible variants. Verify functional equivalence regarding voltage range, output power, and interface type before substituting.
