The HT3382 is an efficient Class D audio power amplifier. In 24V powered stereo (BTL), THD+N=10% conditions, can continue to provide 2*75W/4Ω power output.

The HT3382 has advanced spread spectrum capability to suppress EMI.

In addition, the HT3382 built-in turn-off function minimizes standby current, and also integrates overvoltage protection, DC protection, short circuit protection, thermal protection and power undervoltage abnormal protection to fully prevent failures.
