(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 T

= T
A
.
(2) All limits are guaranteed by testing or statistical analysis.
(3) Typical values represent the most likely parametric norm.
(4) Limits guaranteed by design.

(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 R
L
is relaxed to 10 kΩ, then for
LMV772/LMV772Q/LMV774 temperature limits apply to −40°C to 125°C.
