TDA8758
Notes
1.
2.
0 dB is obtained at the AGC amplifier when applying V
I(p-p)
= 1.0 V on Y channel.
It is recommended that the rise and fall times of the clock are
≥
1 ns. In addition, a ‘good layout’ for the digital and
analog grounds is recommended.
3.
THD (total harmonic distortion) is obtained with the addition of the first five harmonics:
(2nd)2
+
+
+
a) F being the fundamental harmonic referenced at 0 dB for a full-scale sine wave input.
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 = EB
×
6.02 + 1.76 dB.
Measurement carried out using video analyser VM700A, where video analog signal is reconstructed through a
digital-to-analog converter.

The supply voltage ripple rejection is the relative variation of the analog signal (full-scale signal at input) for 0.5 V of
supply variation:
