Notice:
Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification is not
implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.
ELECTRICAL SPECIFICATIONS
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.

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
