"The A + and - inputs of the amplifier go through 1.0 uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio - pin to ground. The output is a high frequency 250 kHz square wave PWM is then 'averaged out' that by the speaker coil - the high frequencies are not heard."
