(1) All limits are guaranteed by testing or statistical analysis.
(2) 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.
(3) CMRR is not linear over the common mode range. Limits are guaranteed over the worst case from 0 to V_CC/2 or V_CC/2 to V_CC.
(4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30mA over long term may adversely
affect reliability.
(5) A 10k pull-up resistor was used when measuring the LMV7235. The rise time of the LMV7235 is a function of the R-C time constant.
(6) Propagation Delay Skew is defined as the absolute value of the difference between t_PDLH and t_PDHL.
