BD5471MUV is a low voltage drive class-D stereo speaker amplifier that was developed for cellular telephones, mobile audio products and the others. LC filters of speaker outputs are unnecessary, and only 7 external components are needed for speaker system. Also, 3.3V regulator in BD5471MUV can use power supply for audio-codec. Efficiency of BD5471MUV is higher than class-AB amplifier, and BD5471MUV can make battery life longer than class-AB. Shutdown current is 0uA typically. Also, start-up time is fast from shutdown to active mode. BD5471MUV can use for some applications that change mode between "shutdown state" and "active state".
