BD28623MUV - ROHM

BD28623MUV 17W+17W Class D Speaker Amplifier

BD28623MUV is a Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and low-power consumption. This IC delivers an output power of 20W+20W. This IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology. With this technology, the IC can achieve high efficiency. In addition, the IC is packaged in a compact b.

Features

 1 Digital Audio Interface I2S format SDATA: 16 / 20 / 24bit LRCLK (fS): 32 kHz/ 44.1kHz / 48kHz BCLK: 64fS (fixed) MCLK: 256fS / 512fS Automatic Identification)
 Low supply current at RESET mode.
 Slew rate controller ; No need snubber circuit (Vcc≤22V)
 Output Feedback Circuitry which prevents decrease of sound quality caused by change of power supply voltage, achieves low noise and low distortion, So the large electrolytic-capacitors for Vcc bypass is able to be eliminated.
 Variable Gain (17dB / 20dB / 26dB)
 Wide power supply voltage range (8.5V to 24V)
 High efficiency, low heat
.
