(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 absolutemaximum- 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 TAS5152 is a third-generation, high-performance, integrated stereo digital amplifier power stage with improved protection system. The TAS5152 is capable of driving a 4- bridge-tied load (BTL) at up to 125 W per channel with low integrated noise at the output, low THD+N performance, and low idle power dissipation.
A low-cost, high-fidelity audio system can be built using a TI chipset, comprised of a modulator (e.g., TAS5508) and the TAS5152. This system only requires a simple passive LC demodulation filter to deliver high-quality, high-efficiency audio amplification with proven EMI compliance. This device requires two power supplies, 12 V for GVDD and VDD, and 35 V for PVDD. The TAS5152 does not require power-up sequencing due to internal power-on reset. The efficiency of this digital amplifier is greater than 90% into 6 , which enables the use of smaller power supplies and heatsinks.
The TAS5152 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, overcurrent protection, undervoltage protection, and overtemperature protection. The TAS5152 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 demodulation output filter.
