Providing two alternative pin-outs to help simplify board layouts, the PAM8013 and PAM8015 each measure just 1.5mm x 1.5 mm x 0.75mm and use a filterless output architecture to minimize the number of external components and total PCB footprint.

The amplifiers provide audio system designers with a differential input and assure low noise performance, high PSRR and good THD+N figures. Output power capability is high as well, providing 3W for a 5V supply into a 4Ω speaker.

The devices feature a wide 2.8V to 5.5V supply voltage operating range to support a variety of different battery cell configurations. With an efficiency as high as 90% and a shutdown current less than 1μA, the amplifiers help maximize system battery life.

To protect the amplifiers from any harmful circuit excesses, they integrate short- circuit protection with auto recovery, over-temperature protection and under- voltage lock-out circuitry.
