HWD2111
Dual 105mW Headphone Amplifier with Digital Volume
Control and Shutdown Mode
General Description
The
HWD2111
is a dual audio power amplifier capable of
delivering 105mW per channel of continuous average power
into a 16鈩?load with 0.1% (THD+N) from a 5V power supply.
audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. Since the
HWD2111
does not require
bootstrap capacitors or snubber networks, it is optimally
suited for low-power portable systems.
The
HWD2111
features a digital volume control that sets the
amplifier鈥檚 gain from +12dB to 鈭?3dB in 16 discrete steps
using a two鈭抴ire interface.
The unity-gain stable
HWD2111
also features an externally
controlled, active-high, micropower consumption shutdown
mode. It also has an internal thermal shutdown protection
mechanism.
