  TAS5142 100W stereo digital amplifier power stage

illustrate   The TAS5142 is the third generation, high performance, with a complete protection system integrated stereo digital amplifier power stage. The TAS5142 is capable of driving 4-bridge up to 100 watts per channel of low-noise output integration, low THD+N performance, and low power idle. A low-cost, hi-fi sound system can be built using TI's chipset, including a modulator (e.g., TAS5508) and TAS5142. The system requires only a simple passive LC filter to demodulate and prove to be EMI compliant to provide high-quality, high-efficiency audio amplification. This unit requires two power 12 GVDD and VDD V and a 32 V power supply for PVDD. The TAS5142 does not require a power-up sequence due to internal power-up reset.   characteristic   2×100 at 10% THD+ to 4 N W-DKD, Offline (1) 2 × 80 10% THD + to 6 Newton W - DKD, offline 2 × 65 10% THD + to 8 n W - DKD, offline 4 × 40 10% THD + to 3 N W - Southeast 4× 30 10% THD+ to 4 N W - Southeast 1 × 160,10% THD + to 3 n W - PBTL 1 × 200 x 10% THD+ to 2 x N W - PBTL "100 dB signal-to-noise ratio (A-weighted) "0.1% THD + n at 1 watt Two thermally enhanced package options: DKD (36-pin PSOP3) Dichlorvos (44-pin HTSSOP) High-efficiency power stage ("90%)" with 140m output MOSFETs There is no protection power sequence when powering up, reset, and power-up Integrated self-protection circuit including undervoltage, overtemperature, overload, short circuit Error reporting When electromagnetically compatible, the design of the recommended system is recommended Intelligent gate drive apply Small/micro sound system
