TAS5186DDVR

Overview

The TAS5186DDVR is a six-channel digital-amplifier power stage from Texas Instruments, housed in a thermally enhanced 44-pin HTSSOP PowerPAD package. It delivers up to 30 W per satellite channel into 6 Ω loads and over 60 W into a 3 Ω subwoofer load at 10% THD+N. The device achieves greater than 90% efficiency with simple passive demodulation filters. Key electrical specifications include a 105-dB A-weighted signal-to-noise ratio, 0.03% THD+N at 1 W, and a maximum PVDD supply voltage of 40 V.

Feature Summary

• Integrates self-protection circuits for undervoltage, overtemperature, overload, and short-circuit conditions.
• Features active-bias control to prevent DC pop noises during startup.
• Includes programmable overcurrent detection to allow the use of lower-cost output filter inductors.
• Compliant with EMI requirements when used with recommended system designs.

Applications

• DVD Receivers
• Home Theater in a Box systems

Procurement Notes

Verify the specific ordering suffix DDVR corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets all applicable RoHS directives and environmental compliance standards mandated by your target market regulations before finalizing procurement contracts.

Selection Notes

Select this component for high-channel-count audio architectures requiring integrated power stages. Ensure the design accommodates the necessary gate-drive and half-bridge supply voltages. Verify that the thermal management strategy adequately addresses the junction-to-case thermal resistance characteristics inherent to the PowerPAD package under maximum load conditions.

Part Context

This part belongs to the PurePath Digital family of audio solutions. It functions as a power stage designed to pair with TI PWM modulators, such as the TAS5086. The architecture eliminates the need for complex power-up sequencing due to internal reset logic, simplifying the overall system integration and reducing the bill of materials for multi-channel audio deployments.
