HWD2038 - ETC

HWD2038 Mono 2W Audio Power Amplifiers

---The HWD2038 is a monolithic integrated circuit that provides DC volume control, and mono bridged audio power amplifiers capable of producing 2W into 4Ωwith less than1.0% THD or 2.2W into 3Ω with less than 1.0%THD. ---The HWD2038 is designed specifically to provide high quality audio from a surface mount package while requiring few external components. It.

Features
