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%)
