TAS5142 100W 立体声数字放大器功率级

The TAS5142 is a third-generation, high-performance, integrated stereo digital amplifier power stage with an improved protection system. The TAS5142 is capable of driving a 4- bridge-tied load (BTL) at up to 100 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, comprising a modulator (e.g., TAS5508) and the TAS5142. 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, at 12 V for GVDD and VDD, and at 32 V for PVDD. The TAS5142 does not require power-up sequencing due to internal power-on reset
