ELECTRICAL CHARACTERISTICS (CONTINUED)
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.
