Notes to the characteristics
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
2. Analog input voltages producing code 00 up to and including FF:
3. Full-scale sine wave (f
4. The analog bandwidth is defined as the maximum input sine wave frequency which can be applied to the device.
5. The analog input settling time is the minimum time required for the input signal to be stabilized after a sharp full-scale
6. Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8K acquisition points per equivalent
7. Intermodulation measured relative to either tone with analog input frequencies of 4.43 MHz and 4.53 MHz. The two
8. Measurement carried out using video analyser VM700A where the video analog signal is reconstructed through a
