Product Summary

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-W bridge-tied load (BTL) at up 100 W per channel with low integrated noise at the output, low THD+N performance, and low idle power dissipation.
