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.

particular test conditions which guarantee specific performance limits. This
assumes that the device is within the Operating Ratings. Specifications are not
guaranteed for parameters where no limit is given, however, the typical value is
a good indication of device performance.
Note 11: Typicals are measured at 25°C and represent the parametric norm.
Note 12: Datasheet min/max specification limits are guaranteed by design, test, or
statistical analysis.
Note 13: Output power is measured at the device terminals.
Note 14: When driving 3Ω loads from a 5V supply the HWD2038MTE must be mounted
to the circuit board and forced-air cooled.
Note 15: When driving 4Ω loads from a 5V supply the HWD2038MTE must be mounted
to the circuit board.
