Product Summary

The TAS3103DBT is an integrated stereo digital amplifier power stage with an advanced protection system. The TAS3103DBT is capable of driving a 6-W 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. The applications of the TAS3103DBT include Televisions, Mini/Micro Audio Systems, DVD Receivers, Home Theaters.
