General Description

BM28723MUV is a 17W+17W Class D stereo Speaker

Amplifier with built-in DSP designed for TVs specifically

for space-saving and low-power consumption.

BM28723MUV features BCD (Bipolar, CMOS, DMOS)

process technology to achieve high efficiency. In

addition, BM28723MUV is packaged in a compact back

surface heatsink type power package to attain low

power consumption, low heat generation without

external heatsink. The package Max output power is

only 17W+17W (When RL=8Ω) as compared to

20W+20W (When RL=8Ω) Max output power of

package with external heat-sink.

The product satisfies all needs for drastic downsizing,

low-profile structures and powerful high quality

playback of sound systems.

Features

Built-in DSP (Digital Sound Processor) for Audio

Signal Processing for TVs

12-Band/ch BQ, 3-Band DRC, Pre-Scaler, Channel

Mixer, Fine Master Volume, Hard Clipper, Level

Meter, etc.

Single Input System for Digital Audio Interface

(No Master Clock Required)

- I2S / LJ / RJ Format

- LRCLK: 32 / 44.1 / 48kHz

- BCLK: 32 / 48 / 64fS

- SDATA: 16 / 20 / 24 bit

Single Output System for Digital Audio Interface

- I2S Format

- SDATA: 16 / 20 / 24 bit

No Snubber Circuit Required (VCCP1,VCCP2≤22V)

because of Slew Rate Control

Output Feedback Circuit which prevents decrease

of sound quality caused by change of power supply

voltage, achieves low noise and low distortion, So

no large electrolytic-capacitors for Vcc bypass is

required.

Wide Range of Power Supply Input Voltage

The monaural output reduces the number of

external parts needed.

High Efficiency and Low Heat Dissipation allowing

Miniaturization, Slim Design, and also Power Saving

of the System

Eliminates pop-noise generated during the power

supply ON/OFF. High quality muting performance is

achieved using the soft-muting technology.

Built-in with Various Protection Functions for Highly

Reliability Design

- High Temperature Protection

- Under Voltage Protection

- Output Short Protection

- DC Voltage Protection for speaker

- Clock Stop Protection

Small Package, It reduces surface mount area

Applications

TVs (LCD, OLED)

Home Audio

Desktop PC

Amusement equipment

Electronic Music equipment, etc.
