VS1003B DAC Output Mono Mode

Post by alipr » Sat 2018-08-04 10:40

Hi everyone
Is it possible to configure DAC outputs of VS1003b so that they would be inverses of each other? (e.g. DAC_Right = -DAC_Left)
I want to play stereo sounds but with a differential input mono audio amplifier connected to VS1003b.
I wander if there is a control register for that.
