ELECTRICAL CHARACTERISTICS (CONTINUED)
Electrical Specifications:
All parameters apply at VDD = 5V, VSS = 0V, VREF = 5V, TA = -40°C to +85°C, fSAMPLE = 100 ksps, and
fCLK = 16*fSAMPLE, unless otherwise noted.

Conditions
Note 1:
This parameter is established by characterization and not 100% tested.
2:
See graph that relates linearity performance to VREF level.
3:
Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity performance,
especially at elevated temperatures. See Section 6.2 “Maintaining Minimum Clock Speed” for more information.
