† 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 CHARACTERISTICS

All parameters apply at VDD = 5V, TA = -40°C to +85°C, fSAMPLE = 200 ksps and fCLK = 16*fSAMPLE, unless otherwise

noted.

Typical values apply for VDD = 5V, TA = +25°C, unless otherwise noted.

Note 1: This parameter is established by characterization and not 100% tested.

2: The sample cap will eventually lose charge, especially at elevated temperatures, therefore fCLK 10 kHz for

temperatures at or above 70°C.
