AC ELECTRICAL CHARACTERISTICS (continued)
(V
unless otherwise noted.)
Note 1: Static linearity parameters are computed from a “best-fit” straight line through the code transition points. The full-scale
Note 2: The offset control input is a self-biased voltage divider from the internal +2.5V reference voltage. The nominal open-circuit
Note 3: The clock input’s termination voltage can be operated between -2.0V and GNDI. Observe the absolute maximum ratings
Note 4: Input logic levels are measured with respect to the V
Note 5: All PECL digital outputs are loaded with 50Ω to V
Note 6: The current in the V
Note 7: Common-mode rejection ratio (CMRR) is defined as the ratio of the change in the transfer-curve offset voltage to the
Note 8: Power-supply rejection ratio (PSRR) is defined as the ratio of the change in the transfer-curve offset voltage to the change
Note 9: Measured with the positive supplies tied to the same potential; V
Note 10: V
