General Description
The BL6305 is a 2.6W high efficiency filter-free class-D audio power amplifier that requires
only three external components.
Features like 88% efficiency, −75dB PSRR, and improved RF-rectification immunity make
the BL6305 ideal for cellular handsets. In cellular handsets, the earpiece, speaker phone, and
melody ringer can each be driven by the BL6305.
Applications
Mobile phone、PDA
MP3/4、PMP
Portable electronic devices
