TMUXS7614D: Clarification on data sheet plot 5-21 "THD+N vs Frequency"

Sanjay

Part Number: TMUXS7614D

Hi Team,

I am using this part for high fedelity application and was going though the THD+N specs and plots. Can you please provide a explanation why the higher ouput span has better THD+N ?

Thanks,
Sanjay

Hi Sanjay,

This is just a representation of the data we took for this device. THD+N happens to be better at the wider voltage range.

Normally we would expect THD to be better at lower amplitudes. Can I expect THD to improve if I decrease the voltage swing? Is it unpredictable with swing as you say?

Thanks!

Hi Auro,

From looking at the data we have, it is likely that THD+N will increase with a lower voltage swing, however I cannot confirm that.

Best,
Katy
