3-W/CH Stereo Filter-less Class-D
Audio Power Amplifier with Auto-Recovery
DESCRIPTION
The EUA2034 is a high efficiency, 3W/channel stereo
class-D audio power amplifier. A low noise, filterless
PWM architecture eliminates the output filter, requiring
only two external components for operation.
Operating from a single 5V supply, EUA2034 is capable of
delivering 3W/ channel of continuous output power to a
4Ω load with 10% THD+N.
The EUA2034 is available in space-saving SOP-16
package.
