Middle Power Class-D Speaker Amplifiers

Class-D Speaker Amplifier

for Digital Input with Built-in DSP

BM5446EFV

No.10075EBT13

●Description

BM5446EFV is a Class D Speaker Amplifier with built-in DSP (Digital Sound Processor) designed for Flat-panel TVs in

particular for space-saving and low-power consumption, delivers an output power of 20W+20W. This IC employs

state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology that eliminates turn-on resistance in the output power

stage and internal loss due to line resistances up to an ultimate level. With this technology, the IC can achieve high

efficiency of 86% (10W+10W output with 8Ω load). In addition, the IC is packaged in a compact reverse heat radiation type

power package to achieve low power consumption and low heat generation and eliminates necessity of external heat-sink

up to a total output power of 40W. This product satisfies both needs for drastic downsizing, low-profile structures and many

function, high quality playback of sound system.

●Features

1) This IC includes the DSP (digital sound processor) for Audio signal processing for Flat TVs.

2) This IC has two input systems of digital audio interface.

(I²S/LJ/RJ format, LRCLK: 32 kHz/ 44.1kHz / 48kHz, SYS_CLK: 256fs / 512fs,

BCLK: 48fs / 64fs, SDATA: 16 / 20 / 24bit)

3) With wide range of power supply voltage, it is possible to operate with single power supply. (Vcc = 10~26V)

4) With high efficiency and low heat dissipation contributing to miniaturization, slim design, and also power saving of the

system.

5) S/N of the system can be optimized by adjusting the gain selection in 16 steps. (20~35dB,1dB/step)

6) With built-in feedback circuitry at the output, prevents the decrease in sound quality due to change in power supply

voltage. In addition, low noise and low distortion are achieved.

7) With a built-in DAC provides best stereo-output for headphone function. As a result, the selection of output of the

digital input in two systems is possible.

8) It has additional S/PDIF output for the LINE output usage.

9) Eliminates pop-noise generated during the power supply on/off. High quality muting performance is realized by using

the soft-muting technology.

10) This IC is built-in with various protection functions for highly reliability design.

(High temperature protection, Under voltage protection, Output short protection, Output DC-Voltage protection and

Clock stop protection).

●Applications

Flat Panel TVs (LCD, Plasma), Home Audio, Desktop PC, Amusement equipments, Electronic Music equipments, etc.
