This system only • 2×25 W at 10% THD+N Into 6-Ω BTL requires a simple passive LC demodulation filter to deliver high-quality, high-efficiency audio • >100-dB SNR (A-Weighted) amplification with proven EMI compliance. This • <0.1% THD+N at 1 W device requires two power supplies, at 12 V for • Thermally Enhanced Package: GVDD and VDD, and at 18 V for PVDD. The – DDV (44-pin HTSSOP) TAS5132 does not require power-up sequencing due to internal power-on reset. The efficiency of this • High-Efficiency Power Stage (>90%) With digital amplifier is greater than 90% into 8 Ω, which 140-m Ω Output MOSFETs enables the use of smaller power supplies and • Power-On Reset for Protection on Power Up heatsinks. Without Any Power-Supply Sequencing The TAS5132 has an innovative protection system • Integrated Self-Protection Circuits Including integrated on chip, safeguarding the device against a Undervoltage, Overtemperature, Overload, wide range of fault conditions that could damage the Short Circuit system. These safeguards are short-circuit • PWM Activity Detector to detect stopped PWM protection, overcurrent protection, undervoltage protection, and overtemperature protection. The inputs and protect the system TAS5132 has a new proprietary current-limiting • Error Reporting circuit that reduces the possibility of device shutdown • EMI Compliant When Used With during high-level music transients. Recommended System Design BTL OUTPUT POWER vs SUPPLY VOLTAGE • Intelligent Gate Drive • Pin Compatible With the TAS5142DDV • Televisions • Mini/Micro Audio Systems • DVD Receivers • Home Theaters The TAS5132 is an integrated stereo digital amplifier power stage with an advanced protection system. The TAS5132 is capable of driving a 6- Ω bridge-tied load (BTL) at up to 25 W per channel with low integrated noise at the output, low THD+N performance, and low idle power dissipation. PurePath Digital™ These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
