TAS5722LRSMR

Overview

The TAS5722LRSMR is a mono Class-D audio amplifier manufactured by Texas Instruments. It delivers 16 W of continuous output power into a 4-Ω load with less than 0.1% THD+N at 5 V supply. The device operates from a single supply voltage ranging from 4.5 V to 17 V and accepts digital inputs compatible with 1.8-V logic levels. It utilizes a 32-pin VQFN (RSM) package designed for surface-mount assembly, supporting high-efficiency audio reproduction in compact electronic systems.

Feature Summary

• Digital input interface compatible with standard audio protocols
• High efficiency Class-D topology for thermal management
• Integrated current sensing capabilities for protection

Applications

• Portable speaker systems
• Smart home audio devices
• Automotive infotainment speakers

Procurement Notes

Verify the complete part number TAS5722LRSMR against official Texas Instruments documentation to ensure correct pinout and electrical specifications. Confirm that the VQFN-32 package variant matches your PCB footprint requirements. Check for moisture sensitivity level compliance during storage and handling procedures prior to soldering.

Selection Notes

Select this component when a mono channel solution is required with digital control interfaces. Ensure the system supply voltage remains within the 4.5 V to 17 V operational range. Verify that the 1.8-V digital I/O compatibility aligns with the host processor or audio codec output levels for reliable signal transmission.

Part Context

This device belongs to the TAS5722L series of digital input Class-D amplifiers. It shares architectural similarities with other members of the family but is distinguished by its specific power rating and package configuration. The RSM suffix indicates the 32-pin VQFN enclosure type used for space-constrained designs.

Replacement Considerations

The TAS5720LRSMR is a documented alternative within the same product family offering similar functionality.
