Oweis - Stereo Class D audio amplifier HT366/HT328/HT338

The HT366/HT328/HT338 is an efficient Class D audio power amplifier.

The HT366/HT328/HT338 feature advanced spread spectrum to suppress EMI.

In addition, the HT366/HT328/HT338 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, which can fully prevent failures.
