BL6305 Datasheet | BELLING

2.6 Watt Mono Filter-Free Class-D Audio Power Amplifier Features Efficiency With an 8-Ω Speaker: 88% at 400 m W 80% at 100 m W 2.1m A Quiescent Current 0.4µA Shutdown Current Optimized PWM Output Stage Eliminates LC Output Filter Internally Generated 250-k Hz Switching Frequency Eliminates Capacitor and Resistor Improved PSRR (- 75 d B) and Wide Supply Voltage (2.5 V to 5.5 V) Eliminates Need for a Voltage Regulator Fully Differential Design Reduces RF Rectification and Eliminates Bypass Capacitor Improved CMRR Eliminates Two Input Coupling Capacitors MSOP8, SOP8, DFN8 package General Description The BL6305 is a 2.6W high efficiency filter-free class-D audio power amplifier that requires only three external ponents. Features like 88% efficiency, - 75d B 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.
