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, over-
current protection and thermal protection function
make the BL6332 ideal for cellular handsets.
Typical Application Circuit
Applications
Mobile phone, PDA
MP3/4, PMP, GPS
