EUA2014
2.5W Stereo Class-D Audio Power Amplifier
with 3D Enhancement
DESCRIPTION
The EUA2014 is a high efficiency, 2.5W/channel stereo
class-D audio power amplifier. A low noise, filterless
PWM architecture eliminates the output filter.
Operating from a single 5V supply, EUA2014 is capable of
delivering 2.5W/ channel of continuous output power to a
4load with 10% THD+N.
The EUA2014 features independent shutdown controls for
each channel. The gain can be selected to 6, 12, 18, or 24
dB utilizing the G0 and G1 gain select pins. High PSRR
and differential architecture provide increased immunity to
noise and RF rectification.
The EUA2014 also includes 3D audio enhancement that
improves stereo sound quality. In devices where the left
and right speakers are in close proximity, 3D enhancement
affects channel specialization, widening the perceived
soundstage.
The EUA2014 is available in space-saving TQFN package,
is an idea choice for mobile phones and other portable
communication devices.
