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.
---The HWD2038 features an externally controlled, low-power consumption shutdown
mode, and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and
pops” during device turn-on.
