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 and

TQFN packages, is an idea choice for mobile phones and

other portable communication devices.
