Datasheet

Middle Power Class-D Speaker Amplifier series

20W+20W

Full Digital Speaker Amplifier

with built-in DSP

BM28720MUV

General Description

Features

BM28720MUV is a Full Digital 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 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. 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.

■

This IC includes the DSP (digital sound processor)

for Audio signal processing for Flat TVs.

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

Channel Mixer, Fine Master Volume,

Hard Clipper, Level Meter etc.

This IC has one input systems of digital audio

interface. (No needs of Master Clock)

- I²S / LJ / RJ format

■

- LRCLK: 32k/44.1k/48KHz

- BCLK: 32fs / 48fs / 64fs

- SDATA: 16 / 20 / 24bit

■

This IC has one output systems of digital audio

interface.

- I²S format

- SDATA: 16 / 20 / 24bit

■

With wide range of power supply voltage.

The monaural output that can reduce the number of

external parts can be used.
