(1) C1 and C2 represent the board line capacitance. They represent about 5 pF with the ADC1206S040/055/070 input
capacitance. Special care has to be taken to minimize this load in order to have the best dynamic performance.
(2) The
α
2H and α3H of the ADC1206S040/055/070 is lower than that measured on the TDA9901. This measurement method is
preferred to conventional methods due to its low contribution to the
α
2H.
(3) The chain measurement shows the harmonic distortion of the TDA9901 as the measurement from ADC1206S040/055/070 is
negligible.
