BL6331 Overview
BL6331 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). BL6331 has a “Professional non-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,.
