Description
The PAM8012 is a 2.0W mono filterless class-D amplifier with high PSRR and differential input that reduce noise. Features like 90% efficiency and small PCB area make the PAM8012 Class-D amplifier ideal for cellular handsets. The filterless architecture requires no external output filter, fewer external components, less PCB area and lower system costs, and simplifies application design. The PAM8012 features anti-saturation function which detect output signal clip due to the over input level and keep the output nonsaturation automatically to get the excellent sound quality. The maximum output power without clip can be set by one resistor at PL pin that to prevent the speaker to be damaged. The PAM8012 features short circuit protection and over temperature protection. The PAM8012 is available in tiny WCSP9 (1.3mm x 1.3mm) and eMSOP10 packages.
