† 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.

See graphs that relate linearity performance to VREF levels.

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.
