TAS5102DAD

Overview

The TAS5102DAD is a 20-watt stereo Class-D audio amplifier from Texas Instruments, designed for high-efficiency audio applications. It accepts PWM digital inputs and operates on an 8V to 23V supply voltage range. The device integrates a DSP controller for motor control tasks alongside audio processing. It is housed in a 32-pin HTSSOP package with PowerPAD technology for thermal management. The component supports open-loop operation and includes analog supply capabilities up to 3V maximum.

Feature Summary

• Integrates a digital signal processor for combined audio and motor control functions
• Accepts pulse-width modulated digital audio inputs directly
• Utilizes PowerPAD thermal enhancement technology for efficient heat dissipation

Applications

• Stereo audio amplification systems requiring digital input interfaces
• Motor control applications utilizing integrated DSP capabilities
• Portable audio devices operating within specified voltage ranges

Procurement Notes

Verify the specific suffix DAD corresponds to the 32-pin HTSSOP package configuration. Confirm that the required supply voltage aligns with the 8V to 23V operational range. Ensure compatibility with PWM input signals rather than analog audio sources. Check for any specific thermal design requirements associated with the PowerPAD mounting style.

Selection Notes

Select this component when a combined audio amplifier and motor controller is needed in a single package. It is suitable for designs requiring direct PWM audio input without external DACs. Consider the thermal performance of the HTSSOP package for the intended enclosure environment. Verify that the system power supply can provide the necessary 8V to 23V range for optimal output power.

Part Context

This part belongs to the TAS5102 family of Class-D audio amplifiers. It is distinct from the PCM5102 series, which are digital-to-analog converters. The TAS5102DAD specifically refers to the version packaged in a 32-lead HTSSOP format. It serves as a solution for integrating audio and motion control in compact electronic designs.
