TAS5760M THD+N

Other Parts Discussed in Thread: TAS5760M

Hi,

In the specification 7.10. Speaker Amplifier in Stereo Bridge Tied Load Mode, the Po(spk) is 11W with PVDD=24V, R=4Ohm and THD+N= 0.1% as highlighted below.

However, figure 7 below seems to say that THD+N is lower than 0.1% which is almost 0.01% at Po=24W. Could you explain about this?

BR,

Ian

    Hi, Ian,

    This is because the 11W are related to the maximum continuous output power (limited by the thermal performance of the board). The instantaneous power (as in the THD+N chart)  in the TAS5760M under the same conditions is considerably larger than the continuous power as the thermal limit is not exeeded.
