PAM8012AZN

PAM8012AZN is a mono filterless class-D amplifier with high PSRR and differential input that reduces noise. Its features, like 90% efficiency and a 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. It features an anti-saturation function that detects output signal clip due to the over-input level and keeps the output nonsaturated automatically to get the excellent sound quality. The maximum output power without clip can be set by one resistor at the PL pin to prevent the speaker from being damaged. The PAM8012 features short-circuit protection and overtemperature protection. Applications include wireless or cellular handsets and PDAs, portable navigation devices, general portable audio devices.
