The efficiency of – 5×30 W @ 6 Ω + 1×60 W @ 3Ω the TAS5186 is greater than 90% when driving 6- Ω satellites and a 3- Ω subwoofer speaker. • 105-dB SNR (A-Weighted) • < 0.05% THD+N @ 1 W The TAS5186 has an innovative protection system integrated on-chip, safeguarding the device against a • Power Stage Efficiency > 90% Into wide range of fault conditions that could damage the Recommended Loads (SE) system. These safeguards are short-circuit protection, • Integrated Self-Protection Circuits overload protection, undervoltage protection, and – Undervoltage overtemperature protection. The TAS5186 has a new proprietary current-limiting circuit that reduces the – Overtemperature possibility of device shutdown during high-level music – Overload transients. A new programmable overcurrent detector – Short Circuit allows the use of lower-cost inductors in the demodu- lation output filter. • Integrated Active-Bias Control to Avoid DC Pop TOTAL HARMONIC DISTORTION + NOISE vs • Thermally Enhanced 44-pin HTSSOP Package OUTPUT POWER • EMI-Compliant When Used With Recommended System Design • DVD Receiver • Home Theater in a Box The TAS5186 is a high-performance, six-channel, digital-amplifier power stage with an improved protec- tion system. The TAS5186 is capable of driving a 6- Ω, single-ended load up to 30 W per each front/satellite channel and a 3- Ω, single-ended subwoofer greater than 60 W at 10% THD+N per- formance. A low-cost, high-fidelity audio system can be built using a TI chipset comprising a modulator (e.g., TAS5086) and the TAS5186. This device does not require power-up sequencing because of the internal power-on reset.
