| BM0210 10W*2 CLASS D+ AUDIO GENERAL DESCRIPTION The BM0210 is two 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. It can deliver output power up to 13W (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 . The BM0210 integrated mute circuit inside , it very suits for application in LCD TV , PDP TV , Projection TV and Car audio and DVD player . 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 4 or 8 ohm speaker No turn on/off noise No mute on/off noise THD+N : <0.2%@1W / 1KHz SNR : 80db Cross noise with other channels : 70db Output power (RMS) is depend on the VDD and load (THD<10%) 12W @ 4ohm /+24V 6W @ 4ohm /+12V 6W @ 8ohm /+24V b=46.7mm Very slim size : 46.7mm*33mm Pin1 = Audio L input Pin2 = A-GND Pin3 = Audio R input Pin4 = +5V Pin5 = DGND (power ground) Pin6 = mute control Pin7 = VDD (+9V ~ +25V) Pin8 = DGND (power ground) Pin9 = LSP , L output to speaker Pin10 = COM (to speaker) Pin11 = COM (to speaker) Pin12 = RSP , R output to speaker a=33mm Gap between pin1 and a is 2.0mm Gap between pin1 and pin8 is 32.86mm Gap between pin1(8) and pin2(9) is 2.54mm Bookly Micro Electronic Limited Cop. 8 9 10 11 12 1 2 3 4 5 6 7 BM0210 10W*2 CLASS D+ AUDIO External application circuit: Power supply (+5V and VDD) +5V VDD +9V ~ +27V 100uF/16V + 220uF/35V DGND Mute="0" Audio L input +5V VDD 6 4 + 1uF Audio R input 1 3 2 5 7 12 9 RSP 11 COM 10 LSP AGND Note1: Mute = 0 , un-Mute = open or 1 Bookly Micro Electronic Limited Cop. + 1uF 8 DGND 4/8 ohm SPEAKER |
