TAS5101IDAPRG4

Overview

The TAS5101IDAPRG4 is a true digital stereo audio amplifier with a PWM stereo power output stage manufactured by Texas Instruments. It integrates the TAS5010 digital audio PWM processor and the TAS5101 power output stage into a single solution. The device accepts digital audio inputs via I2S, left-justified, or right-justified formats. It operates with a PVDD supply range of 12 V to 27 V and a DVDD logic supply of 3.3 V. The amplifier is designed to drive speaker loads, supporting impedances from 4 Ω to 8 Ω.

Feature Summary

• Integrates a digital audio PWM processor and a stereo power output stage for direct digital-to-speaker amplification.
• Supports multiple digital audio input interfaces including I2S, left-justified, and right-justified formats.
• Includes comprehensive protection features such as short-circuit, overtemperature, and undervoltage shutdown capabilities.

Applications

• Stereo audio amplifier designs requiring high efficiency and low distortion.
• Digital audio systems utilizing I2S or standard PCM data interfaces.
• Portable or battery-powered audio equipment due to efficient power stage operation.

Procurement Notes

Verify the specific suffix 'IDAPRG4' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure that the ordering information matches the exact component designation required for your design, as suffixes often denote packaging variations or environmental compliance status.

Selection Notes

Select this component when a complete digital audio amplification solution is needed without external modulators. Confirm that the system power supply can provide the necessary current for the target speaker impedance within the 12 V to 27 V operating range. Verify compatibility with the digital audio source interface formats supported by the integrated TAS5010 processor.

Part Context

This part belongs to the TAS5101 family of true digital audio amplifiers. It combines the functionality of the TAS5010 PWM processor and the TAS5101 power stage. This integration simplifies board layout and reduces component count compared to discrete solutions using separate modulation and power amplification stages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official replacement guide or contact technical support for verified alternatives if this specific package or suffix is unavailable.
