EUA2012A
2.5-W/CH Stereo Filter-less Class-D
Audio Power Amplifier with Auto-Recovery
DESCRIPTION
The EUA2012A is a high efficiency, 2.5W/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, EUA2012A is capable
of delivering 2.5W/ channel of continuous output power to
a 4Ω load with 10% THD+N.
The EUA2012A 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 EUA2012A is available in space-saving WCSP,
TQFN and TSSOP packages, is an idea choice for mobile
phones and other portable communication devices.
