HWD2108
Audio Power Amplifier
Dual 105 mW Headphone Amplifier
General Description
The
HWD2108
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 using surface mount packaging. Since
the
HWD2108
does not require bootstrap capacitors or snub-
ber networks, it is optimally suited for low-power portable
systems.
The unity-gain stable
HWD2108
can be configured by external
gain-setting resistors.
