Harmonics are specified with the SFDR active (SFDR = +5 V). SNR/SINAD specified with SFDR disabled (SFDR = Ground). Specifications subject to change without notice. AC SPECIFICATIONS (V DD = 3.3 V, VCC = 5 V; differential encode input, unless otherwise noted.)

The digital output load during testing is not to exceed an ac load of 10 pF or a dc current of 50 µA. Rise and fall times measured from 10% to 90%. Specifications subject to change without notice. (VDD = 3.3 V, VCC = 5 V; differential encode input, unless otherwise noted.) |
