TAS5102DADR

Overview

The TAS5102DADR is a stereo Class-D audio amplifier manufactured by Texas Instruments. It delivers 20 W of output power and operates with an 8- to 23-V supply voltage range. The device accepts PWM input signals and integrates an audio processor for enhanced performance. It is housed in a 32-pin HTSSOP (DAD) package, designed for high-efficiency digital audio applications.

Feature Summary

• Integrates a digital audio processor within the Class-D architecture
• Supports direct PWM input signal processing
• Provides high-efficiency stereo amplification

Applications

• Digital audio systems requiring integrated processing
• High-efficiency stereo amplifier designs
• Audio equipment utilizing PWM input interfaces

Procurement Notes

Verify the specific suffix DADR corresponds to the 32-pin HTSSOP tape-and-reel packaging configuration. Confirm that the application circuit supports the required 8V to 23V supply range and PWM input logic levels. Ensure thermal management aligns with the 20W output capability in the target enclosure environment.

Selection Notes

Select this component when a combined amplifier and processor solution is needed to reduce bill-of-materials count. It is suitable for designs where PWM inputs are available from the source, eliminating the need for separate DACs or analog front-ends. Verify compatibility with the system's power supply constraints.

Part Context

This part belongs to Texas Instruments' line of digital input Class-D audio amplifiers. It distinguishes itself by embedding an audio processor, allowing for direct digital control and optimization of the audio signal before amplification. This integration simplifies the design process for complex audio systems compared to discrete amplifier solutions.

Replacement Considerations

Check for updated revisions within the TAS5102 family. Verify pinout compatibility if substituting with other TI Class-D amplifiers. Ensure any alternative maintains the 32-pin HTSSOP form factor and PWM input interface requirements.
