Small-sized Class-D Speaker Amplifiers

Analog Input

Stereo Class-D Speaker Amplifier

●Description

BD5471MUV is a low voltage drive class-D stereo speaker amplifier that was developed for note-book PC, cellular phone,

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. BD5471MUV, that

is high-efficiency, low consumption, is suitable for application by using battery. Shutdown current is 0µA 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”.

●Features

1) High power 2.3W typ. (VDD=5V, RL=4Ω, THD+N=10%, stereo input)

High power 1.5W typ. (VDD=5V, RL=8Ω, THD+N=10%, stereo input)

2) Gain selectable by the external control (6, 12, 18, 24dB)

3) Pop noise suppression circuitry

4) Standby function (Mute function) [I

=0uA]

5) Protection circuitry (Short protection [Audio, REG], Thermal shutdown, Under voltage lockout)

6) Built-in 3.3V regulator

7) Built-in BEEP detect circuitry

8) Very small package VQFN024V4040

●Applications

Notebook computers, Mobile electronic applications, Mobile phones, PDA etc.
