BL6305DN - BELLING

BL6305DN 2.6 Watt Mono Filter-Free Class-D Audio Power Amplifier

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. Applic.
