Timing Specifications Limits established by characterization and are not production tested. VDD = 3.0V to 3.6V, fSCLK =18MHz,
fS =1MSPS, VREF = 2.0V; VDD = 4.75V to 5.25V, fSCLK =18MHz, fS = 1MSPS, VREF =2.5V; VCM = VREF unless otherwise noted. Boldface limits apply over
the operating temperature range, -40°C to +85°C.

NOTE:
10. Read the “Acquisition Time” section on page 13 for a discussion of this parameter.
11. During characterization, tDISABLE is measured from the release point with a 10pF load (see Figure 4) and the equivalent timing using the
AD7440/450A loading (25pF) is calculated.
