(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) These voltages represent the dc voltage + peak ac waveform measured at the terminal of the device in all conditions.
DescriptionThe TAS5186 is a high-performance, six-channel, digital-amplifier power stage with an improved protection system.
The TAS5186 is capable of driving a 6-W, single-ended load up to 30 W per each front/satellite channel and a 3-W, single-ended subwoofer greater than 60 W at 10% THD+N performance.
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.
The TAS5186 requires only simple passive demodu-lation filters on its outputs to deliver high-quality,high-efficiency audio amplification. The efficiency of the TAS5186 is greater than 90% when driving 6-W satellites and a 3-W subwoofer speaker.
The TAS5186 has an innovative protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that could damage the system. These safeguards are short-circuit protection, overload protection, undervoltage protection, and overtemperature protection. The TAS5186 has a new proprietary current-limiting circuit that reduces the possibility of device shutdown during high-level music transients. A new programmable overcurrent detector allows the use of lower-cost inductors in the demodu- lation output filter.
