TAS5186ADDVR

Overview

The TAS5186ADDVR is a six-channel digital amplifier power stage from Texas Instruments, designed for high-performance audio systems. It delivers up to 210W total output power, configured as five 30W channels for front/satellite speakers and one 60W channel for a subwoofer at 10% THD+N. Key electrical specifications include a 105dB A-weighted signal-to-noise ratio and 0.07% THD+N at 1W. The device operates with greater than 90% efficiency into recommended loads and utilizes a thermally enhanced 44-pin HTSSOP package.

Feature Summary

• Integrates self-protection circuits including undervoltage, overtemperature, overload, and short-circuit safeguards.
• Features active-bias control to prevent DC pop during power-up sequences.
• Requires only simple passive demodulation filters on outputs for high-fidelity amplification.
• Includes internal power-on reset eliminating the need for complex power-up sequencing.

Applications

• DVD receivers
• Home theater in a box systems

Procurement Notes

Verify the specific suffix 'ADDVR' corresponds to the tape and reel packaging variant when sourcing components. Confirm that the application design adheres to TI's recommended EMI compliance guidelines to ensure regulatory adherence. Cross-reference the datasheet for thermal management requirements associated with the 44-pin HTSSOP package to guarantee reliable operation under maximum load conditions.

Selection Notes

Select this component for multi-channel audio architectures requiring integrated power stages without external modulators. It is suitable for designs prioritizing high efficiency and low distortion in consumer electronics. Ensure the system can accommodate the specific channel configuration of five satellite outputs and one subwoofer output to fully utilize the device capabilities.
