Hi Team, 

Designing the 4channel 20W class D amplifier with TAS6424L-Q1. Chosen the LC filter, L = 3.3uH and C = 1uF based on TI reference material SLOA242A.pdf. 

Is it possible to provide us the THDn Vs Output power graph for the Inductor P/N: VCHA042A-3R3MS6 ?

TI reference material (TPA3251 industry study v1.xls) file contains the THDn Vs Output power graph for different inductors. We are looking for similar data for the chosen inductor.

Please suggest your feedback. 

Thanks
