† Based on analog input voltage of − 1 dBFS referenced to a 1.3 Vpp full-scale input range and using the external voltage references at

fclk = 80 MSPS with AVDD = DVDD = 3.3 V and DRVDD = 3.0 V at 25°C.

4. The analog input bandwidth is defined as the maximum frequency of a −1 dBFS input sine that can be applied to the device for which an extra

3 dB attenuation is observed in the reconstructed output signal.
