Overview
The Texas Instruments TAS5101DAPR is a true digital stereo audio amplifier featuring an integrated PWM power output stage. It accepts direct digital audio inputs, eliminating the need for external DACs. The device drives stereo loads with high efficiency and low distortion. Key electrical parameters include a PVDD supply range of 12 V to 27 V and support for sample rates exceeding 96 kHz via the DBSPD signal. It includes built-in protection against short circuits and overtemperature conditions.
Feature Summary
- Integrates a digital audio PWM processor and a stereo power output stage into a single solution.
- Supports multiple digital audio input formats including I2S, left-justified, and right-justified configurations.
- Includes comprehensive protection features such as shutdown signaling for short circuits and overtemperature events.
Applications
- Stereo speaker amplification in consumer audio systems
- Digital audio processing modules requiring direct digital input
- Embedded audio solutions utilizing PWM output stages
Procurement Notes
Verify the specific ordering suffix 'DAPR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required digital interface settings by checking resistor jumper configurations on the target PCB design.
Selection Notes
Select this component for designs requiring a fully digital stereo amplification path without external modulation components. Consider the 12 V to 27 V PVDD supply requirement and the need for appropriate decoupling to maintain performance under varying load impedances.
Part Context
The TAS5101 belongs to Texas Instruments' family of true digital audio amplifiers. It pairs with the TAS5010 modulator to form a complete digital amplification system. This integration simplifies board layout by reducing the number of discrete components needed for high-power audio applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's latest selection guide for pin-compatible or functionally equivalent alternatives within the same product family.
