BM0120

www.DataSheet4U.com BM0120 20W AUDIO CLASS D+ GENERAL DESCRIPTION The BM0120 is one channel audio amplifier module, using unique close loop and feed forward compensation techniques (CLFFC—IP belong BM) to achieve better THD+N from 20Hz to 20KHz. The module can deliver output power up to 35W (RMS) @4ohm load. The module has mute function with logic high or low control. The voltage gain can be adjusted in the module via fix feedback resistor, the input signal is flexible. No other external components from input to output, and connect to speaker directly. Friendly analog input interface. Very high efficiency , do not need Heat-sink under 20W(RMS) The BM0120 integrated mute circuit inside , it very suits for application in LCD TV , PDP TV , Projection TV and Car audio . APPLICATIONS Car audio -------2/4 channels PDP -------------2.1 channel Projection TV -----2.1 channel LCD TV--------2 channel DVD player Features Wide VDD input range of +9V ~ +26V Reduce system cost with no heat sink and save power Class D+ and CLFFC IP inside Excellent bass frequency without big bypass DC capacitor inside Internal thermal protection Connect to any passive 4 or 8 ohm speaker No mute on/off noise THD+N : <0.2%@1W / 1KHz SNR : 80db Cross noise with other channels : 80db Output power (RMS) is depend on the VDD and load (THD<10%) 30W 20W 13W 15W @ 4ohm /+24V @ 4ohm /+18V @ 4ohm /+12V @ 8ohm /+24V b=46mm Pin1 = Audio input Pin2 = A-GND Pin3 = GND Pin4 = +5V Pin5 = Mute control Pin6 = VDD (+9V ~...
