When connecting a device to a speaker set, you often hear ground noise between the two. To combat this problem, we've developed a circuit implementation to eliminate ground noise in TI headphone amplifiers and line drivers. This demo will help ensure the audio quality is as you intend it no matter how a customer connects the circuit.
