(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device such that TJ = TA.

(2)

All limits are guaranteed by testing or statistical analysis.

(3)

Typical values represent the most likely parametric norm.

(4)

Limits guaranteed by design.

(5)

RL is connected to mid-supply. The output voltage is set at 200mV from the rails. VO = GND + 0.2V and VO = V

+ −0.2V

(6)

For LMV772/LMV772Q/LMV774, temperature limits apply to

−40°C to 85°C.

(7)

For LMV772/LMV772Q/LMV774, temperature limits apply to

−40°C to 85°C. If RL is relaxed to 10 kΩ, then for

LMV772/LMV772Q/LMV774 temperature limits apply to

−40°C to 125°C.
