BL6332

BL6332 3W Anti-Clip Class-D Audio Power Amplifier Features Output Power - 3.0W (VDD=5.0V, RL =4Ω, THD+N=10%) - 1.8W (VDD=5.0V, RL =8Ω, THD+N=10%) Low THD+N and Low Noise High S/N Ratio to 95dB Low EMI Improved PSRR (−80dB) and Wide Supply Voltage (2.5 V to 5.0V) Eliminates Need for a Voltage Regulator Over-current and Thermal Protection function Pop noise reduction function Available in space-saving package: 9-Bump WLCSP General Description BL6332 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). BL6332 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 BL6332 ideal for cellular handsets.
