BD5471MUV - 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.

Features

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) [ISD=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.

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”.
