DY0A14D9H IC Chip for Bluetooth Audio Receiver

The DY0A14D9H is a Bluetooth chip found in the cheap Bluetooth audio receiver from china

There is no datasheet of this ic available. When opened the receiver, i found many leads of this IC not connected in the circuit, this could be the leads for mute,next,previous etc functions.

The bad thing about this cheap receiver is that it is mono and has weak sound output to some amplifiers, perhaps this is because the lazy Chinese engineers didn’t connect this chip in stereo mode, that’s what i assume since there are many leads of it unconnected.

No more information of this chip is available for now. If i find a datasheet, i will post here
