TDA8716
Notes
1. Voltage offset BOTTOM (V_OB) is the difference between the analog input which produces data outputs equal to 00
and the reference voltage BOTTOM (V_RB), at T_amb = 25 °C. Voltage offset TOP (V_OT) is the difference between
reference voltage TOP (V_RT) and the analog input which produces data outputs equal to FF, at T_amb = 25 °C.
2. The analog input is not internally biased. It should be externally biased between V_RB and V_RT levels.
3. The TDA8716 can only withstand one or two 10K or 100K ECL loads in order to work-out timings at the maximum
sampling frequency. It is therefore recommended to minimize the printed-circuit board load by implementing the load
device as close as possible to the TDA8716.
4. Full-scale sinewave; f_i = 4.43 MHz; f_CLK, f_CLK = 100 MHz.
5. Effective bits are obtained via a Fast Fourier Transformer (FFT) treatment taking 4 K acquisition points per period.
The calculation takes into account all harmonics and noise up to half of the clock frequency (NYQUIST frequency).
Conversion to SNR: SNR = EB (dB) × 6.02 + 1.76.
