TIMING CHARACTERISTICS
Serial Interface
DVDDx = 2.7 V to 5.5 V; AVDDx = 4.5 V to 5.5 V; AGNDx = DGND = 0 V; all specifications TMIN to TMAX, unless otherwise noted. The
AD5384 must remain powered up when part of a multidevice system with a common I2C bus. Guaranteed by design and characterization,
not production tested. All input signals are specified with tr = tf = 5 ns (10% to 90% of DVDDx) and are timed from a voltage level of 1.2 V.
