Arduino PAM8302 2,5 W Klasse D Audio Verstärker Amp PAM8302 Raspberry Pi Neu
1,81 €
The A+ and A- inputs of the amplifier go through 1.0uF 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 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard.
