AW8010AFCR

The AW8010A is a proprietary TDD-suppression, ultra-low EMI, mono Class-D audio power amplifier. It employs proprietary RNS (RF-TDD Noise Suppression) technology to effectively suppress TDD noise generation, providing strong rejection of RF interference caused by conducted power supply and radiated emissions during phone hands-free operation. Proprietary EEE (Enhanced Emission Elimination) technology dramatically reduces EMI across the full bandwidth, delivering more than 20dB margin under FCC standards for a 60cm audio cable. An integrated proprietary timing control circuit provides comprehensive pop-click suppression, eliminating transient noise that may occur during power-on, power-off, wake-up, and shutdown operations. Built-in overcurrent protection and overtemperature protection safeguard the device from damage under abnormal operating conditions, with automatic recovery once the fault condition is removed. Available in a compact 1.5mm×1.5mm FC-9 package, rated for an operating temperature range of -40℃ to 85℃. The filterless PWM modulation scheme eliminates the LC output filter required by conventional Class-D amplifiers, improving efficiency and enabling a smaller footprint, lower-cost solution.
