AC PERFORMANCE CHARACTERISTICS
VDD1 = 4.75 V to 30 V, VSS1= −16.5 V to 0 V, AGND = DGND = 0 V, VREFIN = 2.5 V external, DVCC = 1.7 V to 5.5 V, RLOAD = 1 kΩ for all
ranges except 0 V to 16 V and 0 V to 20 V for which RLOAD = 2 kΩ, CLOAD = 200 pF, all specifications TMIN to TMAX, unless otherwise noted.
