General Description

The BL6306 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 BL6306 ideal for cellular handsets. In cellular handsets, the earpiece, speaker phone, and

melody ringer can each be driven by the BL6306.
