一.产品概述
CXAD4168 is a 3-W (VDD=5.0V, RL=4Ω) high efficiency filter-free class-D audio power amplifier in a wafer chip scale package (WLCSP). CXAD4168 has a “Professional Anti-Clip output control circuit” which reducing distortion of output signal due to either the over level input signal or power supply voltage down with battery. Features like high efficiency, −80dB PSRR, overcurrent protection and thermal protection function make the CXAD4168ideal for cellular handsets.
