(1) All limits are ensured by testing or statistical analysis.
(2) CMRR is not linear over the common mode range. Limits are guaranteed over the worst case from 0 to VCC/2 or VCC/2 to VCC.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
(4) Propagation Delay Skew is defined as the absolute value of the difference between tPDLH and tPDHL.
(5) A 10k pullup resistor was used when measuring the LMV7235. The rise time of the LMV7235 is a function of the R-C time constant.
