(1)

Typical Values represent the most likely parametric norm.

(2)

All limits are specified by testing or statistical analysis.

(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)

The LMV7219 comparator has internal hysteresis. The trip points are the input voltage needed to change the output state in each

direction. The offset voltage is defined as the average of Vtrip+ and Vtrip−, while the hysteresis voltage is the difference of these two.
