(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)

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.

(4)

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.

(5)

Propagation Delay Skew is defined as the absolute value of the difference between tPDLH and tPDHL.
