regulator

[7] Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8000 acquisition points per equivalent fundamental

period. The calculation takes into account all harmonics and noise up to half of the clock frequency (Nyquist frequency). Conversion to

signal-to-noise ratio: SINAD = ENOB × 6.02 + 1.76 dB.

[8] Intermodulation measured relative to either tone with analog input frequencies of 4.43 MHz and 4.53 MHz. The two input signals have

the same amplitude and the total amplitude of both signals provides full-scale to the converter.

[9] Measurement carried out using video analyzer VM700A, where the video analog signal is reconstructed through a digital-to-analog

converter.

[10] Output data acquisition: the output data is available after the maximum delay time of td(o). For the 50 MHz version it is recommended to

have the lowest possible output load.
