TIMING CHARACTERISTICS
DVCC = 2.5 V to 5.5 V; VDD = 9 V to 16.5 V; VSS = 8 V to 16.5 V; VREF = 5 V; AGND = DGND = SIGGND = 0 V; CL = 200 pF to GND;
RL = open circuit; gain (M), offset (C), and DAC offset registers at default values; all specifications TMIN to TMAX, unless otherwise noted.

1 Guaranteed by design and characterization, not production tested.
2 All input signals are specified with tr = tf = 2 ns (10% to 90% of DVCC) and timed from a voltage level of 1.2 V.
