BL6305 BL6305 * 的详细介绍

BL6305 BL6305 * Mono Filter-Free Class-D Audio Power Amplifier

Features

_ Efficiency With an 8-_ Speaker:

88% at 400 mW

80% at 100 mW

_ 2.1mA Quiescent Current

_ 0.4μA Shutdown Current

_ Optimized PWM Output Stage Eliminates LC Output Filter

_ Internally Generated 250-kHz Switching Frequency Eliminates Capacitor and Resistor

_ Improved PSRR (−75 dB) 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 CapacitorBL6305 BL6305 *

_ Improved CMRR Eliminates Two Input Coupling Capacitors

_ MSOP8, SOP8, DFN8 package

General DescriptionBL6305 BL6305 *

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 makeBL6305 BL6305 *

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 phonePDA

_ MP3/4PMP

_ Portable electronic devices
