TDA8706A
Notes
1. In addition to a good layout of the digital and analog ground, it is recommended that the rise and fall times of the clock
must not be less than 1 ns.
2. Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8K 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.
3. Output data acquisition: the output data is available after the maximum delay time of td.
Timing (fclk = 40 MHz; CL = 20 pF); Tamb =25 °C; see Fig.3
