TAS5186DDV

Overview

The TAS5186DDV is a six-channel digital-amplifier power stage from Texas Instruments. It delivers up to 30 W per satellite channel into 6 Ω and over 60 W for the subwoofer channel into 3 Ω at 10% THD+N. The device features a 105-dB A-weighted signal-to-noise ratio, greater than 90% efficiency into recommended loads, and integrated self-protection against undervoltage, overtemperature, overload, and short circuits.

Feature Summary

• Six-channel digital amplifier power stage with independent half-bridge outputs
• Integrated active-bias control to prevent DC pop during startup
• Programmable overcurrent detection allowing use of lower-cost output filter inductors
• Thermally enhanced 44-pin HTSSOP PowerPAD package

Applications

• DVD receivers
• Home theater in a box systems

Procurement Notes

Verify the specific ordering suffix DDV corresponds to the 44-pin HTSSOP PowerPAD package. Confirm that system designs utilize the recommended TI chipset architecture, such as pairing with a TAS5086 modulator, to ensure proper PWM interface compatibility and optimal performance metrics.

Selection Notes

Select this component for high-power multi-channel audio applications requiring high efficiency and low distortion. Ensure the design accommodates the required 40 V power-stage supply and 12 V gate-drive supply. Verify thermal management capabilities are sufficient for the intended power dissipation levels under maximum load conditions.

Part Context

This part belongs to the PurePath Digital family of audio amplifiers. It functions as a power stage designed to work in conjunction with separate PWM modulators. The architecture separates the modulation logic from the high-power output stage to optimize thermal performance and system flexibility.
