Diodes Incorporated has introduced two high-efficiency, low-noise 3W mono Class D audio amplifiers, the PAM8013 and PAM8015, both in a tiny QFN1515-9L package measuring just 1.5mm x 1.5mm x 0.75mm Designed to support the miniaturization of portable products such as MP3 players, tablets and smartphones.
The PAM8013 and PAM8015 offer two different pin options to simplify board layout to meet different design requirements. This family of amplifiers eliminates the need for an external LC filter output structure, reducing the number of external components and reducing PCB area.
The two amplifiers feature a differential input mode that guarantees low noise performance, high power supply rejection ratio, and good total harmonic distortion. They provide up to 3W of continuous output power capability for 4Ω loads when powered from a 5V supply.
The new device is guaranteed to operate from a 2.8V to 5.5V supply voltage range, supporting a wide range of battery configurations. Their output efficiency is as high as 90%, and the shutdown current is less than 1μA, which helps to extend the battery life of the system.
To prevent harmful circuit overload, the two amplifiers integrate protection circuits such as short-circuit protection, over-temperature protection, and undervoltage lockout circuits with self-recovery.
