ELECTRICAL SPECIFICATIONS (CONTINUED)
Electrical Characteristics:
Unless otherwise noted, all parameters apply at VDD = 5V, VREF = 5V,
TA = -40°C to +85°C, fSAMPLE = 200 ksps and fCLK = 18*fSAMPLE. Unless otherwise noted, typical values apply for
VDD = 5V, TA = +25°C.

Conditions
Note 1:
This parameter is established by characterization and not 100% tested.
2:
See graphs that relate linearity performance to VREF levels.
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”
, “Maintaining Minimum Clock Speed”, for more information.
