Product specification

TDA8761A

8. Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8 K 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: S/N = ENOB × 6.02 + 1.76 dB.

9. Intermodulation measured relative to either tone with analog input frequencies of 10.0 and 10.10 MHz. The two input

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

10. Measurement carried out using video analyser VM700A, where the video analog signal is reconstructed through a

digital-to-analog converter.

11. Output data acquisition: the output data is available after the maximum delay time of td.
