CS2 DATA SHEET HWD2038 —— Mono 2W Audio Power Amplifiers with DC Volume Control z General Description ---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 incorporates a DC volume control that consists of 31 steps that are individually selected by a variable DC voltage level on the volume control pin. The range of the steps are from 0dB - 78dB. Each gain step corresponds to a specific input voltage range.
