TPA6130A2: THD+N VS frequency and Noise curve

Antony Fu

Part Number: TPA6130A2

Hello team,

Since the THD+N performance of in phase mode is worse than out of phase mode, and our datasheet only shows the out of phase performance for THD+N VS frequency curve, so whether we have the curve of in phase mode?

We have the output noise parameter in datasheet too, and it only has one value such as 9uVrms, so whether we have the curve of noise VS frequency?

Thanks and Best Regards,

Hi Antony,

In Phase measurements are not too far from out of phase. Attached is a plot for THD+N vs Freq with ~63mW output on 16ohm loads.

Regarding the noise, I'm also attaching a plot for ICN (idle channel noise) of both channels.
