TAS5186DDVG4

Overview

The TAS5186DDVG4 is a six-channel digital-amplifier power stage from Texas Instruments. It delivers 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 achieves greater than 90% efficiency with simple passive demodulation filters. Key electrical parameters include a 105-dB A-weighted SNR, 0.07% THD+N at 1 W, and a 40 V PVDD supply voltage. It utilizes a thermally enhanced 44-pin HTSSOP PowerPAD package.

Feature Summary

• Integrated self-protection circuits including undervoltage, overtemperature, overload, and short-circuit safeguards.
• Active-bias control mechanism designed to eliminate DC pop noises during power-up or switching events.
• Programmable overcurrent detector allowing for lower-cost inductor selection in output filter designs.
• Proprietary current-limiting circuitry that reduces device shutdown probability during high-level music transients.

Applications

• DVD Receivers
• Home Theater in a Box systems

Procurement Notes

Verify the specific ordering suffix DDVG4 against the manufacturer's official documentation to confirm pinout compatibility and thermal specifications. Ensure the component matches the exact datasheet revision SLES136. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the final assembly process.

Selection Notes

Select this component when designing high-efficiency multi-channel audio systems requiring integrated protection. It pairs effectively with TI PWM modulators like the TAS5086. Consider the 44-pin HTSSOP package for thermal management needs. Verify load impedance ranges to ensure operation within specified efficiency and distortion limits.

Part Context

This part belongs to the PurePath Digital amplifier family. It functions as a power stage driven by external PWM processors. The TAS5186 provides the output amplification while relying on companion chips for modulation. This architecture allows for flexible system design with high fidelity and low component count.
