Decoupling to AGND.

I checked the DNL error of various TDA1541A grades: S1, Taiwan, no mark, and R1. From bit #0 to bit #7 the error is <0.1 LSB for all grades. These bits are not included in the table.

The full scale THD shows some minor difference:
S1: 0.00026% / 0.00030% (L/R)
TW: 0.00039% / 0.00040%
no mark: 0.00037% / 0.00032%
R1: 0.00033% / 0.00037%

Hi thanks,

which year for the Taiwan, please ?

Now you have a S1 (if non taiwan) & a Taiwan no grade, are you not surprised they sound so different ? I was amazed by that !
