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

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”,
for more information.
