TAS5186DDVRG4

Overview

The TAS5186DDVRG4 is a six-channel, digital-amplifier power stage from Texas Instruments. It delivers total output power of 210 W at 10% THD+N, configured as five 30 W satellite channels and one 60 W subwoofer channel. The device features a 105-dB signal-to-noise ratio (A-weighted) and maintains efficiency greater than 90% into recommended loads. It operates with a half-bridge supply voltage up to 40 V and 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 prevent DC pop noises during operation.
• Programmable overcurrent detection allowing for lower-cost demodulation filter inductors.
• EMI-compliant performance when implemented with recommended system design guidelines.

Applications

• DVD Receivers
• Home Theater in a Box systems

Procurement Notes
