• Supports multiple digital audio input interfaces including I2S and TDM
• Includes comprehensive protection mechanisms for thermal and electrical faults

Applications

• Home theater systems
• Active loudspeakers
• Audio amplifiers

Procurement Notes

Verify the specific suffix DKD to confirm the package type and tape-and-reel configuration. Ensure compatibility with the intended digital audio source interface. Check for RoHS compliance status in the latest datasheet revision before procurement.

Selection Notes

Select this component when a compact solution combining DSP and power amplification is required. Consider the thermal management requirements due to the integrated power stage. Verify that the system voltage and load impedance match the amplifier's operational limits.

Part Context

This part belongs to the TAS51xx series of stereo digital amplifier power stages from Texas Instruments. These devices are designed to replace traditional analog amplifier designs by integrating DSP functions directly into the power stage, reducing external component count and board space.

Replacement Considerations

Compatible alternatives within the same family include the TAS5152DKD and TAS5132DKD. Verify pinout compatibility and performance specifications such as output power and efficiency before substitution.
