Class D Amp headphones grounding circuit
Insert a 470uF capacitor into the VO_P output with the capacitor + lead going to the IC. Now you are no longer shorting out the DC bias voltage at the output pins. Use small cell-phone type headphones or earbuds to get enough volume. You need 2 of these ICs for stereo sound. This IC cannot drive studio grade headphones, at least not to any useful volume.
