CKE CD4440CS/LA4440 Board (PCB) is to be making two channel audio power amplifier IC board with inbuilt in dual channels enables it for stereo and bridge amplifier ready board.in this PCB is provides In dual mode it gives 6 W per channel output. It has good ripple rejection of 46dB, small residual noise, built in over voltage and surge voltage protection etc. ideal feature of the IC is its pin-to-pin protection. Features of 4440 Built in two channels to use as Mono and Stereo Dual mode 6W x 2 channel 46 dB Ripple rejection 18V Max. Power handling and 12V typical Good channel separation and low distortion Built in Audio Muting function and Pin-to-Pin protection Surge protection circuit input supply of 12v DC from transformer is also rectified diode points are located on the PCB.and 5v DC points is also provided for Bluetooth connections
