General Description
Key Specifications
The HWD2111 is a dual audio power amplifier capable of ^{n THD+N at 1kHz, 105mW continuous average output}
delivering 105mW per channel of continuous average power
power into 16Ω

external components. Since the HWD2111 does not require
bootstrap capacitors or snubber networks, it is optimally _Features
suited for low-power portable systems.
n Digital volume control range from +12dB to −33dB
The HWD2111 features a digital volume control that sets the _{n LD and MSOP surface mount packaging}
amplifier’s gain from +12dB to −33dB in 16 discrete steps
using a two−wire interface.
n "Click and Pop" suppression circuitry
n No bootstrap capacitors required
The unity-gain stable HWD2111 also features an externally
controlled, active-high, micropower consumption shutdown
