描述 Description

BM28723MUV是針對(duì)電視等的省空間、節(jié)能用途而開(kāi)發(fā)的、搭載17W+17W DSP(數(shù)字聲音處理器)的立體聲D類(lèi)揚(yáng)聲器放大器。采用最先進(jìn)的BCD（Bipolar, CMOS, DMOS）工藝技術(shù)，以及小型背面散熱型的功率封裝，具備低功耗、低發(fā)熱量，無(wú)需散熱片即可實(shí)現(xiàn)RL=8Ω時(shí)最大17W+17W的輸出（另行采取散熱片等散熱措施時(shí)最大20W+20W）?是同時(shí)滿足音響類(lèi)系統(tǒng)大幅小型化、薄型化以及強(qiáng)感染力、高音質(zhì)播放兩方面需求的產(chǎn)品。

特性 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
