TAS5261DKDR

Overview

The TAS5261DKDR is a Texas Instruments audio amplifier featuring a 315-W mono bridge-tied load digital power stage. It operates as a Class-AB output device with stereo channel configuration. The unit supports a 3 Ohm audio load impedance and functions within a supply voltage range of 10.8 V to 13.2 V. Total Harmonic Distortion plus Noise is rated at 0.05%. The component utilizes an HSSOP-36 package for surface mount installation and maintains an operating temperature range from 0°C to +70°C.

Feature Summary

• Integrates a high-power mono digital power stage designed for efficient audio amplification.
• Employs Class-AB output topology to drive low-impedance loads effectively.
• Features single input type compatibility for simplified system integration.

Applications

• High-fidelity home theater systems requiring powerful mono subwoofer channels
• Professional audio equipment utilizing digital power stages
• Automotive audio subsystems compatible with specified voltage ranges

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details through official manufacturer documentation before procurement. Ensure the specific suffix DKDR matches design requirements, as variations exist within the product family. Cross-reference datasheet revisions to validate electrical parameters against current production batches.

Selection Notes

Select this component for designs requiring a dedicated mono digital power stage with Class-AB output characteristics. Verify that the 10.8 V to 13.2 V supply voltage range aligns with the target system architecture. Ensure the HSSOP-36 package footprint fits the PCB layout constraints. Consider the 3 Ohm load impedance specification when designing speaker connections.
